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.

[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`.
