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'. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@273034 91177308-0d34-0410-b5e6-96231b3b80d8
