Change Details

Depend on the compiler to provide a correct implementation of `max_align_t`. If `__STDCPP_NEW_ALIGNMENT__` is missing and C++03 mode has been explicitly enabled, provide a minimal fallback in `<new>` as alignment of the largest primitive types.

Always depend on the compiler to have a correct implementation of max_align_t in stddef.h and don't provide a fallback. For pre-C++11, require __STDCPP_NEW_ALIGNMENT__ in <new> as provided by clang in all standard modes. Adjust test cases to avoid testing or using max_align_t in pre-C++11 mode and also to better deal with alignof(max_align_t)>16. Document requirements of the alignment tests around natural alignment of power-of-two-sized types.
