Can we add a comment here explaining why we use the comp kind complement? (e.g. Ge => LeU)

Yeah that's fair. I realized when writing the comments that we only need to perform the complementary comparisons for lt and le given we need to have the PF checks for gt and ge so we're not saving any instructions by swapping those so we no longer swap those.
