This also removes some tests which were redundant, wrong, or never run. Specifically, - `libcxx/utilities/meta/stress_tests/*` were never run and are of questionable usefulness - `libcxx/utilities/template.bitset/includes.pass.cpp` is completely redundant and partially incorrect Also notably, `libcxx/language.support/support.c.headers/support.c.headers.other/math.lerp.verify.cpp` has been refactored to only test the standard mandate.
