objective-c: warn if implementation of a method in category

masks an existing method in its primary class, class extensions,
and primary class's non-optional protocol methods; as primary
class, or one of its subclass's will implement this method.
This warning has potential of being noisy so it has its own
group.  // rdar://7020493
