Zinovy Nis	07ac2bd4d0	[PATCH] Force LoopReroll to reset the loop trip count value after reroll. It's a bug fix. For rerolled loops SE trip count remains unchanged. It leads to incorrect work of the next passes. My patch just resets SE info for rerolled loop forcing SE to re-evaluate it next time it requested. I also added a verifier call in the exisitng test to be sure no invalid SE data remain. Without my fix this test would fail with -verify-scev.
