This PR enables superclass compatibility checks for untyped methods when
--check-untyped-defsis set. IMO this behavior is correct as--check-untyped-defsis essentially "treat everything as if there were: Anyannotations on all arguments", hence checking arg count and names is sound.This PR, however, allows
@overrideon classes that have Any fallback as those are often coming from unfollowed imports. This PR started as an attempt to reject@overrideon untyped defs not found in superclass, but I think it's better to just run all compatibility checks if the flag is enabled.
