088e6015b2 Fix PR#31454 - 'basic_string<T>::push_back() crashes if sizeof(T)>sizeof(long long)'. We were mishandling the small-string optimization calculations for very large 'characters'. This may be an ABI change (change the size of) strings of very large 'characters', but since they never worked, I'm not too concerned.

68b20ca4d9 Fix building libc++ with the macOS 10.13 SDK with -mmacosx-version-min=10.12 or lower. 
The 10.13 SDK always defines utimensat() (with an availability(macosx=10.13) annotation)
and unconditionally defines UTIME_OMIT, so use the compile-time availability macros
on Apple platforms instead.

For people statically linking libc++, it might make sense to also provide an opt-in
option for using __builtin_available() to dynamically check for the OS version,
but for now let's do the smallest thing needed to unbreak the build.

Based on a patch by Eric Fiselier <eric@efcs.ca>: https://reviews.llvm.org/D34249
Fixes PR33469.

13177172d0 Fix initialization of array<const T, 0> with GCC. 
Previously, when handling zero-sized array of const objects we
used a const version of aligned_storage_t, which is not an array type.
However, GCC complains about initialization of the form: array<const T, 0> arr = {};

This patch fixes that bug by making the dummy object used to represent
the zero-sized array an array itself. This avoids GCC's complaints
about the uninitialized const member.

0b47a655ac Implement LWG2989: path's streaming operators allow everything under the sun. 
Because path can be constructed from a ton of different types, including string
and wide strings, this caused it's streaming operators to suck up all sorts
of silly types via silly conversions. For example:

using namespace std::experimental::filesystem::v1;
std::wstring w(L"wide");
std::cout << w; // converts to path.

This patch tentatively adopts the resolution to LWG2989 and fixes the issue
by making the streaming operators friends of path.

122c064a76 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.
