IRGen: Emit categories for ObjC class extensions. Emit ObjC stubs and categories for methods defined in extensions of ObjC-compatible classes. This makes extensions of ObjC classes available to ObjC in statically compiled code. For immediate-mode code we'll still need to dynamically register extension methods using the ObjC runtime.
