The expected 'filesystem::path::compare' result states that for different
path only result sign contains the information about passed arguments
(not its integer value). This is due it uses the output of other compare
functions (basic_string_view and char_traits) without further handling and
char_traits uses memcmp for final buffer comparison.
However for GLIBC on AArch64 the code:
int ret = memcmp ("b/a/c", "a/b/c", 1);
Results in '64' where for x86_64 it results in '1'.
This patch fixes the expected 'filesystem::path::compare' by normalizing
all the results before assert comparison.

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'.
