ObjC lifetime: pull sugar off when the qualifiers conflict. It's possible to have multiple local ObjCLifetime qualifiers. When there is a conflict, we can't stop after we reach a type that is directly qualified. We need to keep pulling sugar off and removing the ObjCLifetime qualifers. rdar://25804796 Differential Revision: http://reviews.llvm.org/D20843 llvm-svn: 271409
