[PATCH] D90402: [LoopFlatten] Run it earlier, just before IndVarSimplify

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

Quick question on loop flattening preserving analyses. As far as I understand loop passes are required to preserve a number of analyses across all loops. Although I'm not sure if that is new or old pass managers. It's because function level analyses can't easily be rerun inside loop passes.

Would that be true for loop flattening? If we did enable this, would the pass pipeline still look OK?
