[PATCH] D76483: [DivRemPairs] Freeze operands if they can be undef values

Hi,

I wrote https://bugs.llvm.org/show_bug.cgi?id=45885 about a crash which starts happening with this patch.

My guess is that isGuaranteedNotToBeUndefOrPoison doesn't like "weird" code that may appear in blocks that are not reachable from entry.
