[Objective-C Sema]This patch fixes the warning when clang issues

"multiple methods named '<selector>' found" warning by noting 
the method that is actualy used. It also cleans up and refactors
code in this area and selects a method that matches actual arguments
in case of receiver being a forward class object.
