Objective-C subscript expressions report errors when a subscript method is not declared in the base class. However, prior to this commit, qualified id types were not checked. This commit ensures that an appropriate error is reported when a subscript method is not declared in any of the protocols that are included in the qualified id type. rdar://33213924 llvm-svn: 307642
