+When processing @synthesize, treat ivars in a class extension the same as ivars in the class @interface, 
+and treat ivars in a superclass extension the same as ivars in the superclass @interface.
+In particular, when searching for an ivar to back an @synthesize, do look at ivars in the class's own class 
+extension but ignore any ivars in superclass class extensions.
