I think the patch still misses a description of the motivation for the restriction in `getLoopGuardBranch`. I see why the restriction would be helpful for LoopFusion, but it seems like there could be other uses cases that do not require that restriction (e.g. if one wants to use the guard for reasoning about values in the loop).
