JF Bastien 2fec6dc56e Mark deduction guide tests as failing on apple-clang-9 
As discussed here: http://lists.llvm.org/pipermail/cfe-dev/2018-May/058116.html
The tests fail on clang-5, as well as apple-clang-9. Mark them as such.

Eric Fiselier 59cdf90ac8 [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`.

Nirav Dave 936ff58476 Revert "[libc++] Fix PR35491 - std::array of zero-size doesn't work with non-default constructible types." 
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.

Eric Fiselier 192622dc49 Make array<const T, 0> non-CopyAssignable and make swap and fill ill-formed. 
The standard isn't exactly clear how std::array should handle zero-sized arrays
with const element types. In particular W.R.T. copy assignment, swap, and fill.

This patch takes the position that those operations should be ill-formed,
and makes changes to libc++ to make it so.

This follows up on commit r324182.
