[PATCH] D73245: Depend stddef.h to provide max_align_t for C++11 and provide better fallback in <new>

Require `__STDCPP_NEW_ALIGNMENT__` in C++03 mode. Prefer it over `max_align_t` in a number of tests when allocation alignment is desired. Adjust some tests to do minimal sanity checking of the alignment for C++03 only. Add an explicit check that `__STDCPP_NEW_ALIGNMENT__`  is more general than `max_align_t` if both are present.
