[PATCH] D102635: [LoopUnroll] Use tripcount from exiting header, if latch not exiting.

[Philip Reames via Phabricator via llvm-commits]

@fhahn I'm willing to defer to you here.  If you're really sure the TripCount is always interpreted as an upper bound, you can land and move forward.  From your description, it really sounds like this code is duplicating a lot of logic already existing in SCEV.  As a cleanup, it would be nice if we named the variables appropriately and used scev's existing distinction between exact and max trip counts.
