Apply workaround for Intel-16

Without this I see:
```
/boost/core/noncopyable.hpp(42): error: defaulted default constructor cannot be constexpr because the corresponding implicitly declared default constructor would not be constexpr
        BOOST_CONSTEXPR noncopyable() = default;
```
See: https://travis-ci.org/boostorg/type_traits/jobs/4722892817
Not sure if later Intel versions also require this... still working on that.

-
-[section Overview]
-
-The header `<boost/core/allocator_access.hpp>` provides the class and function
-templates to simplify allocator use. It provides the same functionality as the
-C++ standard library `std::allocator_traits` but with individual templates for
-each allocator feature.
-
-It also adds additional functionality for allocator aware exception safe
-construction and destruction of arrays.
-
-These facilities also simplify existing libraries by avoiding having to check
-for `BOOST_NO_CXX11_ALLOCATOR` and conditionally use `std::allocator_traits`.
-
-[endsect]
-
-[section Examples]
-
-The following example shows these utilities used in the definition of
-an allocator-aware container class:
-
-```
-template<class T, class A = boost::default_allocator<T> >
-class container
-    : boost::empty_value<typename boost::allocator_rebind<A, T>::type> {
-public:
-    typedef T value_type;
-    typedef A allocator_type;
-    typedef typename boost::allocator_size_type<A>::type size_type;
-    typedef typename boost::allocator_difference_type<A>::type difference_type;
-    typedef value_type& reference;
-    typedef const value_type& const_reference;
-    typedef typename boost::allocator_pointer<A>::type pointer;
-    typedef typename boost::allocator_const_pointer<A>::type const_pointer;
-    // ...
-};
-```
-
-In C++11 or above, aliases such as `boost::allocator_pointer_t<A>` can be used
-instead of `typename boost::allocator_pointer<A>::type`.
-
-The following example allocates storage for an array of `n` elements of `T`
-using an allocator `a` and constructs `T` elements in that storage. If any
-exception was thrown during construction of an element, the constructed
-elements are destroyed in reverse order.
-
-```
-template<class A>
-auto create(A& a, std::size_t n)
-{
-    auto p = a.allocate(n);
-    try {
-        boost::allocator_construct_n(a, boost::to_address(p), n);
-    } catch (...) {
-        a.deallocate(p, n);
-        throw;
-    }

-{
-    little = see below,

-
-The values of `endian::big` and `endian::little` are distinct. `endian::native` is equal to `endian::big` on
-big endian platforms, equal to `endian::little` on little endian platforms, and a distinct value on platforms

-
-Note that you should not rely on `little` and `big` having any specific values, because the C++20 standard

-[section Revision History]
-
-[section Changes in 1.82.0]
-
-* Added [link core.snprintf `boost/core/snprintf.hpp`] header with portable definitions of `snprintf`, `vsnprintf` and
-  their `wchar_t` counterparts.
-* Deprecated `boost/core/is_same.hpp` and `boost::core::is_same`. The header will be removed in a future release.
-  Users are advised to use [@http://www.boost.org/doc/libs/release/libs/type_traits/doc/html/index.html Boost.TypeTraits]
-  or C++ standard library type traits instead.
-
-[endsect]
-
-[section Changes in 1.81.0]
-
-* [link core.empty_value `empty_value`] members are now marked as `constexpr`.
-* Added [link core.fclose_deleter `fclose_deleter`], a deleter that calls `std::fclose` on a pointer to `std::FILE`.
-* Bit manipulation utilities in [link core.bit `boost/core/bit.hpp`] now explicitly require unsigned integers on input.
-  ([@https://github.com/boostorg/core/issues/129 #129])
-* `bit_width` now returns `int` instead of a value of the input argument type. This follows the
-  resolution of [@https://cplusplus.github.io/LWG/issue3656 LWG3656].
-
-[endsect]
-
-[section Changes in 1.80.0]
-
-* In [link core.allocator_access `boost/core/allocator_access.hpp`], added detection of `construct` and `destroy`
-  members of an allocator.
-* `boost/core/alloc_construct.hpp` header is now deprecated and will be removed in a future release. Its functionality
-  was moved to [link core.allocator_access `boost/core/allocator_access.hpp`]. In particular, new methods
-  `allocator_construct_n` and `allocator_destroy_n` were added for allocating and destroying arrays.
-* Worked around MSVC bug that failed to compile [link core.span `span`] in C++17 mode when Boost.Range headers were included.
-  ([@https://github.com/boostorg/core/issues/105 #105], [@https://github.com/boostorg/core/pull/115 PR#115])
-* Added support for 128-bit integer types in [link core.type_name `type_name`].
-* In [link core.pointer_traits `pointer_traits`], pointer rebinding now supports C++03 compilers.
-
-[endsect]
-
-[section Changes in 1.79.0]
-
-* Added `boost::allocator_traits`, an implementation of `std::allocator_traits`.
-* Made `boost::pointer_traits` SFINAE friendly.
-* `boost/iterator.hpp` is deprecated and will be removed in a future release. The header defines the
-  `boost::iterator` template, which is equivalent to `std::iterator` in the `<iterator>` header. However,
-  since `std::iterator` is itself deprecated in C++17, users are advised to remove the use of `boost::iterator`
-  or `std::iterator` from their code.
-* Added `boost::core::verbose_terminate_handler`, a utility function intended
-  to be passed to `std::set_terminate` that prints information about the
-  uncaught exception to `stderr`.
-
-[endsect]
-
-[section Changes in 1.78.0]
-
-* Added a generic implementation to `boost/core/cmath.hpp`, enabled when `BOOST_CORE_USE_GENERIC_CMATH`
-  is defined or when the platform does not provide the necessary facilities in `<cmath>`.
-* Added `boost::core::type_name`, a utility function that returns the name of a type as a string.
-* Added `boost::span`, a C++11 implementation of C++20's `std::span`.
-
-[endsect]
-
-[section Changes in 1.77.0]
-
-* `boost/core/uncaught_exceptions.hpp` has been modified for compatibility with Mac OS 10.4 and older.
-
-[endsect]
-
-[section Changes in 1.76.0]
-
-* Added implicit conversion between compatible reference wrappers.
-* Added `boost/core/cmath.hpp`, a portable implementation of the floating point classification functions from `<cmath>`.
-* Added `boost/core/bit.hpp`, a portable implementation of the C++20 standard header `<bit>`.
-* Fixed `BOOST_TEST_EQ`, `BOOST_TEST_NE` for character types under C++20.
-* Revised allocator access utilities (now support VS2013, and no workarounds use `allocator_traits`.)
-
-[endsect]
-
-[section Changes in 1.74.0]
-
-* Implemented the allocator access utilities which provide a replacement for `allocator_traits`
-  with individual traits and functions for each facility. They support the C++11 allocator model
-  when possible and provide a fallback for C++98 compatibility.
-* Added `BOOST_TEST_WITH` to Lightweight Test.
-
-[endsect]
-
-[section Changes in 1.71.0]
-
-* Added functions `alloc_construct`, `alloc_construct_n`, `alloc_destroy`, and `alloc_destroy_n`
-  in `<boost/core/alloc_construct.hpp>` for allocator aware and exception safe construction and
-  destruction of objects and arrays.
-* Added constexpr functions `first_scalar` in `<boost/core/first_scalar.hpp>` for obtaining a pointer
-  to the first scalar element of an array. Given a pointer of type `T*` they return a pointer of type
-  `remove_all_extents_t<T>*`.
-* Added class template `noinit_adaptor` in `<boost/core/noinit_adaptor.hpp>` which is an allocator adaptor
-  that converts any allocator into one whose `construct(ptr)` performs default initialization via placement
-  `new`, and whose `destroy(ptr)` invokes the `value_type` destructor directly.
-* Added class template `default_allocator` in `<boost/core/default_allocator.hpp>`, which can serve as a minimal
-  default allocator that has interface similar to C++20 `std::allocator`, supports configurations with disabled
-  exceptions and does not have `std` as an associated namespace. The allocator uses `operator new` and
-  `operator delete` for allocation.
-* In `<boost/core/uncaught_exceptions.hpp>` header, added workarounds for better compatibility with QNX SDP 7.0
-  when libc++/libc++abi libraries are used.
-* The `<boost/detail/sp_typeinfo.hpp>` header is now marked as deprecated and will be removed in a future release.
-  `<boost/core/typeinfo.hpp>` should be used instead.
-
-[endsect]
-
-[section Changes in 1.69.0]
-
-* Implemented `boost::empty_value`, for library authors to conveniently leverage the Empty Base Optimization to
-  store objects of potentially empty types.
-* Implemented `boost::quick_exit` to provide the C++11 standard library facility `std::quick_exit` functionality.
-* Reduced the number of statics in Lightweight Test, and employ lighter abort behavior for MSVC compilers upon
-  failure to call `boost::report_errors`.
-
-[endsect]
-
-[section Changes in 1.67.0]
-
-* Updated `to_address` and `pointer_traits` to reflect the design adopted for C++20 in
-  [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0653r2.html P0653R2].
-
-[endsect]
-
-[section Changes in 1.65.0]
-
-* Implemented `pointer_traits` for C++03 and higher, that implements
-  [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0653r0.html P0653r0].
-* Added `BOOST_TEST_GT` and `BOOST_TEST_GE` to Lightweight Test.

-[section Overview]
-
-The header <boost/core/default_allocator.hpp> provides the class template
-`boost::default_allocator` to serve as a minimal default allocator that:
-
-* Like C++2a's `std::allocator`, does not provide members such as `construct()`
-and `destroy()` to be eligible for optimizations by allocator-aware code that
-detects the absence of these members to provide more optimal construction.
-* Supports `BOOST_NO_EXCEPTIONS` in allocation.
-* Does not have `std` as an associated namespace.

-for a container.

-
-The header `<boost/core/snprintf.hpp>` provides portable definition of [@https://en.cppreference.com/w/c/io/fprintf `snprintf`],
-`vsnprintf` and their corresponding `wchar_t` counterparts. On a platform that supports these functions in the standard library,
-these definitions are equivalent to the standard functions. On other platforms (mainly, older MSVC versions) these functions
-are emulated through non-standard functions that have similar behavior.
-
-Depending on the standard library, certain implementation differences are exposed to the user:
-
-* Any non-standard behavior with respect to string format description are not hidden by the emulation.
-* Returned value of `boost::core::snprintf` in case if the output buffer is too small may not be equal to the number of characters
-  that would have been written if the buffer was large enough. It is, however, equal or larger than the buffer size,
-  which still allows the caller to detect the buffer overflow condition. The formatted output is still properly null-terminated
-  in this case.
-
-[note Unlike `snprintf`, `swprintf` does not return the number of characters to be written if the output buffer is too small
-but returns -1 instead. Furthermore, `swprintf` may or may not produce characters in the output buffer in this case.]
-
-[section Example]
-``
-char buf[10];
-int n = boost::core::snprintf(buf, sizeof(buf), "%d", i);
-if (n < 0)
-    throw std::runtime_error("Formatting error");
-if (n >= sizeof(buf))

-[section Overview]
-
-This header <boost/core/span.hpp> provides class template `span`, which is a
-view over a sequence of objects. It implements the C++20 standard library
-`std::span` facility. This implementation supports C++11 and higher.
-
-In addition to referencing the sequence of objects, the span knows the count of
-objects. There are two kinds of spans:
-
-* Dynamic size (`span<T>` or `span<T, dynamic_extent>`)
-* Static size (`span<T, N>`)
-
-Dynamic size spans have a count that can be a value known at run time. Static
-size spans have a count that must be known at compile time.
-
-[endsect]
-
-[section Examples]
-
-The following snippet shows a function to compute a SHA1 hash whose parameters
-and return type use spans.

-```
-auto sha1(boost::span<const unsigned char> input,
-    boost::span<unsigned char, SHA_DIGEST_LENGTH> ouput)

-[section Header <boost/core/string_view.hpp>]
-
-The header `<boost/core/string_view.hpp>` defines `boost::core::string_view`,
-a portable and interoperable implementation of `std::string_view`.
-
-Unlike `boost::string_view`, `boost::core::string_view` has implicit
-conversions from and to `std::string_view`, which allows Boost libraries that
-support C++11/C++14 to use it in interfaces without forcing users to forgo the
-use of `std::string_view` in their code.

-
-The header `<boost/core/type_name.hpp>` defines the function
-template `boost::core::type_name<T>()` that returns a string
-representation of the name of `T`, suitable for logging or
-diagnostic display purposes.
-
-The result is similar to `boost::core::demangle( typeid(T).name() )`,
-but it's made more regular by eliminating some of the platform-specific
-differences and extra template parameters of the standard library
-container types.
-
-For example, `type_name< std::map<std::string, int> >()` returns
-`"std::map<std::string, int>"` and not
-
-```
-  std::map<std::__cxx11::basic_string<char, std::char_traits<char>,
-    std::allocator<char> >, int, std::less<std::__cxx11::basic_string<char,
-    std::char_traits<char>, std::allocator<char> > >, std::allocator<
-    std::pair<std::__cxx11::basic_string<char, std::char_traits<char>,
-    std::allocator<char> > const, int> > >
-```
-
-or
-
-```
-  class std::map<class std::basic_string<char,struct std::char_traits<char>,
-    class std::allocator<char> >,int,struct std::less<class std::basic_string<

-    std::allocator<struct std::pair<class std::basic_string<char,struct
-    std::char_traits<char>,class std::allocator<char> > const ,int> > >
-```
-
-The return values aren't guaranteed to be stable across Boost releases.
-
-Compilation with `-fno-rtti` is supported, but the returned type names aren't
-guaranteed to be particularly useful or unique.
