Philip Reames bdf608477e [SCEV] Add smin support to getRangeRef ...

We were failing to compute trip counts (both exact and maximum) for any loop which involved a comparison against either an umin or smin. It looks like this simply got missed when we added smin/umin to SCEV.  (Note: umin was submitted separately earlier today.  Turned out two folks hit this at the same time.)
