Previously the <experimental/filesystem> didn't guard its
contents in any dialect. However, the implementation implicitly
requires at least C++11, and the tests have always been marked
unsupported in C++03. This patch puts a header guard around the
contents to avoid exposing them before C++11.
Additionally, it replaces all of the usages of _NOEXCEPT or
_LIBCPP_CONSTEXPR with the keyword directly, since we can
expect the compiler to implement those by now.

As I move towards implementing std::filesystem, there is a need to
make the existing tests run against both the std and experimental versions.
Additionally, it's helpful to allow running the tests against other
implementations of filesystem.
This patch converts the test to easily target either. First, it
adds a filesystem_include.hpp header which is soley responsible
for selecting and including the correct implementation. Second,
it converts existing tests to use this header instead of including
filesystem directly.

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'.
