David Green a9bfe02006 [LoopRotate] Rotate loops with loop exiting latches ...

If a loop has a loop exiting latch, it can be profitable
to rotate the loop if it leads to the simplification of
a phi node. Perform rotation in these cases even if loop
rotate itself didnt simplify the loop to get there.
