  Changed paths:

  Log Message:
  -----------
  Remove redundant implicit cast creation.

FindCompositePointerType has already cast the operands to the composite
type for us in the case where it succeeds.

  Add a FIXME and corresponding test coverage for some suspicious behavior
forming composite ObjC pointer types in comparisons.

  Log Message:
  -----------
  Clean up and slightly generalize implementation of composite pointer
type computation, in preparation for P0388R4, which adds another few
cases here.

We now properly handle forming multi-level composite pointer types
involving nested Objective-C pointer types (as is consistent with
including them as part of the notion of 'similar types' on which this
rule is based). We no longer lose non-CVR qualifiers on nested pointer
types.
