Tim Shen 379ae77a60 [SCEV] Strengthen StrengthenNoWrapFlags (reapply r334428).
Summary:
Comment on Transforms/LoopVersioning/incorrect-phi.ll: With the change
SCEV is able to prove that the loop doesn't wrap-self (due to zext i16
to i64), disabling the entire loop versioning pass. Removed the zext and
just use i64.
