Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.
This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

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.
