952eaecfc6 Implement P0513R0 - "Poisoning the Hash"
Summary:
Exactly what the title says.

This patch also adds a `std::hash<nullptr_t>` specialization in C++17, but it was not added by this paper and I can't find the actual paper that adds it.

See http://wg21.link/P0513R0 for more info.

If there are no comments in the next couple of days I'll commit this

bad1d6c248 Fix PR31378 - std::list::remove should not require a default constructible allocator.
In list::remove we collect the nodes we're removing in a seperate
list instance. However we construct this list using the default
constructor which default constructs the allocator. However allocators
are not required to be default constructible. This patch fixes the
construction of the second list.

6e9a694dce Add Filesystem TS -- Complete
Add the completed std::experimental::filesystem implementation and tests.
The implementation supports C++11 or newer.

The TS is built as part of 'libc++experimental.a'. Users of the TS need to
manually link this library. Building and testing the TS can be disabled using
the CMake option '-DLIBCXX_ENABLE_FILESYSTEM=OFF'.

Currently 'libc++experimental.a' is not installed by default. To turn on the
installation of the library use '-DLIBCXX_INSTALL_EXPERIMENTAL_LIBRARY=ON'.

d24c465bea Replace __cplusplus comparisons and dialect __has_feature checks with TEST_STD_VER.
This is a huge cleanup that helps make the libc++ test suite more portable.
Patch from STL@microsoft.com. Thanks STL!

7b193f7797 More of N4258 implementation. Mark all of our test_allocators as noexcept constructible. Make the constructors for basic_string noexcept all the time (under C++14). Update tests to reflect the new world order. More to come.

061d0cc4db There were two identical files named 'min_allocator.h'. Move one of them to /support and delete the other. Then adjust all the tests that used them to include the moved one. No functionality change.
