Argyrios Kyrtzidis bcf2bdc922 Point diagnostics that complain about a use of a selector in an objc message, to the selector location.
Previously it would point to the left bracket or the receiver, which can be particularly
problematic if the receiver is a block literal and we end up point the diagnostic far away
for the selector that is complaining about.
