edfdc498b8 [libcxx] Make return value of array<T, 0>.data() checked only for libc++ 
The section array.zero says: "The return value of data() is unspecified".
This patch marks all checks of the array<T, 0>.data() return value as
libc++ specific.

Reviewed as https://reviews.llvm.org/D55364.
Thanks to Andrey Maksimov for the patch.

a320121c4c [libcxx] Add missing <cstddef> includes in tests 
Some tests use type std::max_align_t, but don't include <cstddef> header
directly. As a result, these tests won't compile against some conformant
libraries.

6cb35ede81 [libc++] Fix PR35491 - std::array of zero-size doesn't work with non-default constructible types. 
Summary:
This patch fixes llvm.org/PR35491 and LWG2157  (https://cplusplus.github.io/LWG/issue2157)

The fix attempts to maintain ABI compatibility by replacing the array with a instance of `aligned_storage`.

Revert "Fix initialization of array<const T, 0> with GCC."
Revert "Make array<const T, 0> non-CopyAssignable and make swap and fill ill-formed."

This reverts commit r324182, r324185, and r324194 which were causing issues with zero-length std::arrays.
