Nice, thanks for landing this Doug.

Some random comments:

1. Should this have a __has_feature check?

2. Should the dox in the manual mention -f[no-]objc-infer-related-result-type?

3. Please add a doxygen comment to CheckObjCMethodOverrides

4. Why add the RelatedResultType bit to ObjCMethodDecl?  Isn't it always determinable from the selector?
