[PATCH] D71383: [LoopGuard] Instructions in loop preheader and loop exit must be safe to execute speculatively.

[Whitney Tsang via Phabricator via llvm-commits]

Whitney added a comment.

I did a test with a loop that has a call which may throw inside, and SCEV is able to calculate the trip count, add recurrence of the induction variable, etc. Maybe we can keep getLoopGuardBranch() as is, and not worry about instructions which not guaranteed to transfer execution to successors? What do you think @Meinersbur?
