Reapply [MergeICmps] Don't require GEP

Recommit without changes over 53abe3ff66a54117308352d379837c7d3229f8d6,
which addressed the cause of the reported crash.

-----

With opaque pointers, the zero-offset load will generally not use
a GEP. Allow a direct load without GEP, which is treated the same
way as a zero-offset GEP.
