This patch adds a separate `extensions` directory, since there are quite a few extensions in libc++ that aren't necessarily libc++-specific. For example, the tests currently in `libcxx/test/libcxx/extensions` should also pass with libstdc++, since they originally added the extension. This also "documents" what users are allowed to rely on and what parts are just libc++ tests to make sure our implementation is behaving as we expect, which may be subject to change. This patch also formats the tests and refactors `.fail.cpp` tests to `.verify.cpp` tests.
