[SCEV] Extend type hint in analysis output to all backedge kinds
This extends the work from 7755c26 to all of the different backend taken count kinds that we print for the scev analysis printer. As before, the goal is to cut down on confusion as i4 -1 is a very different (unsigned) value from i32 -1.
