I have no strong preference to the option name and I think there are probably a better names than what I chose. I was e.g. undecided between `on` and `always`, `user` and `non-intrinsic`, and `-fmodule-mismatch-check` and `-fignore-module-checksums` (its negation).

My bikesheeding for `-fmodule-verify` would be that it sounds like it would verify the module individually, but is meant to check the concistency between modules.

`-Wno-module-verify` comes from the warning diagnostic handling system. Making it an alias to non-warning switches is not that easy.
