Daniel James 8229aa6b3c Stop throwing exception in allocator copy/assignment ...

The standard specifies that all of these "shall not exit via an
exception". The containers have been exception safe when these throw,
but the 'noexcept' attribute on 'get_allocator' will terminate if an
exception is thrown in the copy constructor.

The standard doesn't specify a default constructor, so that is allowed
to throw an exception (not just pedantry, this makes sense if an
allocator has shared data that's allocated in the initial constructor).
