When importing an Objective-C class, category, or extension that explicitly conforms to protocols, mirror any protocol methods that aren't also declared in the class/category/extension within the extension. Among other things, this makes sure that "-hash" and "-isKindOfClass:" are available on NSObject (they come from the NSObject protocol). Fixes <rdar://problem/13074691>. Swift SVN r3920
