This revision is now accepted and ready to land.

Sorry for the delay. This doesn't fix the original case unfortunately, as that version doesn't start with an icmp. The test case is a little different with the loads feeding the loop condition.
But sounds like it should be an improvement, so LGTM (I would suggest committing after the branch ;) )
