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. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@328475 91177308-0d34-0410-b5e6-96231b3b80d8
