The loop unrolling part looks good to me, too.  I am not an expert of SCEV.

                 bool AllowRuntime, bool AllowExpensiveTripCount,
-                bool UseUpperBound, unsigned TripMultiple, LoopInfo *LI,
-                ScalarEvolution *SE, DominatorTree *DT, AssumptionCache *AC,

Thank you for catching my mistake.
