  Log Message:
  -----------
  [SemaObjC] Add a warning for @selector expressions that potentially refer to objc_direct methods

By default, only warn when the selector matches a direct method in the current
class. This commit also adds a more strict off-by-default warning when there
isn't a non-direct method in the current class.
