I can see how ConstraintElimination may benefit from dealing with regular compares, but wouldn't CE provide a more amenable IR for SimplifyCFG to work with? I just wonder whether we might risk to miss potential SimplifyCFG opportunities if we postpone this. Running InstCombine, AggressiveIC, and CE together early in the pipeline looks beneficial too for CFG simplification purposes, AFAICT.
