   poke the isLookupPtrRegClass() method directly.

2. Make PointerLikeRegClass contain a 'kind' int, and store it in
   the existing regclass field of TargetOperandInfo when the
   isLookupPtrRegClass() predicate is set.  Make getRegClass pass
   this into TargetRegisterInfo::getPointerRegClass(), allowing
   targets to have multiple ptr_rc things.
