Disable Wmissing-noreturn for test files

Browse Source 
Adding unreachable to `FAIL` and `SKIP` made Clang become very good
at figuring out that tests of `FAIL` and `SKIP` will never return
and thus could be marked as [[noreturn]].

To avoid introducing lot of warning suppression noise into the
test files, we just disable it instead.
