Another SCEV issue from PR2607; essentially the same issue, but this
time applying to the implicit comparison in smin expressions. The
correct way to transform an inequality into the opposite
inequality, either signed or unsigned, is with a not expression.

I looked through the SCEV code, and I don't think there are any more
occurrences of this issue.
