GCC emits a warning instead of an error when using an unavailable Objective-C protocol, so now Clang's behavior is more strict in this case, but more consistent. We will need to see how much this fires on real code and determine whether this case should be downgraded to a warning. Fixes <rdar://problem/8213093>. llvm-svn: 109033
