zhongduo added a comment to D73059: [IndVarSimplify] Extend previous special case for load use instruction to any narrow type loop variant to avoid extra trunc instruction.

@az This problem was exposed in a small test case that we were working on. For that particular one, we have around 8% but it might be the result of preventing other optimization from happening. I didn't see significant impact with spec.
