  -----------
  [FuzzMutate] Support opaque pointers

Avoid checks that are irrelevant for opaque pointers, and pick
load/GEP types independently of the pointer type.

The GEP case at least could be done more efficiently by directly
generating a type, but this would require some significant API
changes.
