First I removed all of the uses of _LIBCPP_STD_VER and added LIT UNSUPPORTED tags to prevent the tests from being run in older standard dialects. Second I increased the time tolerances used in some tests when testing with Thread Sanitizer because thread sanitizer make these tests take longer. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@245793 91177308-0d34-0410-b5e6-96231b3b80d8
