Add new checker-specific attribute 'objc_ownership_cfretain'. This is the same
as 'objc_ownership_cfretain' except that the method acts like a CFRetain instead
of a [... retain] (important in GC modes). Checker support is wired up, but
currently only for Objective-C message expressions (not function calls).
