Subject: Remove the code from IVUsers that attempted to handle casted
 induction variables in cases where the cast isn't foldable. It ended up being
 a pessimization in many cases. This could be fixed, but it would require a
 bunch of complicated code in IVUsers' clients. The advantages of this
 approach aren't visible enough to justify it at this time.
