Ah. Well, I feel better now -- I couldn't see how my change would
be causing an execution failure regression.... It should only have been
avoiding the segfault!
I'm going to ponder the SCEV code in question a little more -- while
it's easy enough to filter out unwanted stuff in VRP, I'm really
more concerned that SCEV gave us junk in the first place.
