Don't suppress unimplemented type family warnings with DeriveAnyClass
Summary:
For some asinine reason, we were suppressing warnings when
deriving associated type family instances with `DeriveAnyClass`. That seems
like a bad idea. Let's not do that.
Along the way, I noticed that the error contexts associated with these
newly emitted warnings were less than ideal, so I did some minor refactoring
to improve the story there.
