[PATCH] D92575: [mac/lld] Run tests with -fatal_warnings by default

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

The tests that check for warnings (there's currently just one) all use `%no_fatal_warnings_lld`. That's still testable with this patch.

The motivation here is that lld/MachO warns on options that are marked HelpHidden and there were several instances were someone implemented a flag but forgot to remove HelpHidden, and then lld still warned about the flag not being implemented even though it is. This prevents that type of error. Also see discussion on D92455 <https://reviews.llvm.org/D92455> -- I strongly prefer this patch here over that other one.
