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/alloc_construct.hpp> provides function templates
-`alloc_construct`, `alloc_construct_n`, `alloc_destroy`, and `alloc_destroy_n`
-for allocator aware and exception safe construction and destruction of objects
-and arrays.
-
-[endsect]
-
-[section Example]
-
-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::alloc_construct_n(a, boost::to_address(p), n);
-    } catch (...) {
-        a.deallocate(p, n);
-        throw;
-    }
-    return p;
-}
-```
-
-[endsect]
-
-[section Reference]
-
-```

-
-template<class A, class T>

-[endsimplesect]
-
-[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.
-
-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`.

-
-[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.
-
-```

-`default_allocator`.

-
-[section Overview]
-
-The header <boost/core/noinit_adaptor.hpp> provides the class
-template `boost::noinit_adaptor` that converts any allocator into
-one whose `construct(ptr)` performs default initialization via placement new,
-and whose `destroy(ptr)` invokes `value_type` destructor directly.
-
-[endsect]
-
-[section Examples]
-
-The following example shows use of this allocator adaptor to achieve default
-initialization of elements of a trivial type, which are later assigned values.
-
-```
-#include <boost/core/noinit_adaptor.hpp>
-#include <numeric>
-#include <vector>
-
-int main()
-{
-    std::vector<int, boost::noinit_adaptor<std::allocator<int> > > v(5);
-    std::iota(v.begin(), v.end(), 1);
-}
-```
-
-The `allocate_shared_noinit` function templates are now implemented simply
-using `allocate_shared` with `noinit_adaptor`.
-
-```
-template<class T, class A>
-enable_if_t<is_unbounded_array_v<T>, shared_ptr<T> >
-allocate_shared_noinit(const A& a, size_t n)

-
-[section Overview]
-
-The header <boost/core/nvp.hpp> provides the class template `boost::nvp` that
-pairs a name (`const char*`) with the address of a value (`T*`). It is the new
-implementation of the NVP type previously provided by the Boost Serialization
-library. This type now lives in the Core library so that other Boost libraries
-can support named value serialization without taking a dependency on the
-Serialization library.
-

-
-The following snippet shows use in a member serialize function:
-
-```
-template<class A>
