  Log Message:
  -----------
  Reapply [InstCombine] Don't try converting opaque pointer bitcast to GEP

Reapplied without changes -- this was reverted together with an
underlying patch.

-----

Bitcasts having opaque pointer source or result type cannot be
converted into a zero-index GEP, GEP source and result types
always have the same opaque-ness.
