ObjectiveC [Sema]. This patch makes sure that all inherited

properties (direct or indirect) setter/getter (or declared 
methods as well) are seen by the method implementation type 
matching logic before declaration of method in super class 
is seen. This fixes the warning coming out of that method mismatch.
