This reduces the optimization remarks for unrolling to only include the unroll count, and whether it is a complete unroll, partial unroll or runtime unroll. The information about `ULO.TripMultiple` and `BreakoutTrip` is removed, as it is not compatible with multiple exits. The alternative would be to instead add information about all exits to the optimization remarks, but this doesn't seem particularly useful to me.
