  [ConstantFold] Remove unnecessary cast of zero gep fold (NFCI)

Zero GEPs will be optimized away entirely, except in the cases
which this transform also excludes (splat, inrange).

This reverts commit 2182561b7ba675ca87356c02474eecb6ecfaa23f.

The all-ones special case in this case isn't redundant. Will redo
the change while preserving it.
