stdlib: fast enumeration: stop relying on stack promotion optimization for correctness Fast enumeration clients rely on pointer identity of the fast enumeration state struct. We were using 'withUnsafeMutablePointers' to get a pointer to the state stored in a property, but we were relying on stack promotion optimization to access the stored property itself rather than the writeback buffer. rdar://19165256 Swift SVN r25146
