Summary: Following the discussion on the libcxx-dev mailing list (http://lists.llvm.org/pipermail/libcxx-dev/2019-May/000358.html), this implements the new policy for handling experimental features and their deprecation. We basically add a deprecation warning for std::experimental::filesystem, and we remove a bunch of <experimental/*> headers that were now empty.
