Quite a few libcxx tests seem to follow the format: #if _LIBCPP_STD_VER > X // Do test. #else // Empty test. #endif We should instead use the UNSUPPORTED lit directive to exclude the test on earlier C++ standards. This gives us a more accurate number of test passes for those standards and avoids unnecessary conflicts with other lit directives on the same tests.
