[PATCH] D30757: [LoopUnroll] Don't peel loops where the latch isn't the exiting block

This version looks good to me too.

PS: Can we have a similar problem in the regular loop unrolling?

----------------
I'd prefer to have LCSSA-ed version of the loop in the test. And, by the way, do we need `%sum`, `%plus` and `%incsum` at all? Maybe remove them to make the test even smaller?
