Akira Hatanaka 60ec474c05 [ObjCArc] Do not dereference an invalidated iterator. ...

Fix a bug in ARC contract pass where an iterator that pointed to a
deleted instruction was dereferenced.

It appears that tryToContractReleaseIntoStoreStrong was incorrectly
assuming that a call to objc_retain would not immediately follow a call
to objc_release.
