Don't think sharing is good option for this patch. RBLegalizeRules are much more flexible and I would assume faster because of "FastPredicateSlot".
If we add more IDs that would work with LLTs only we could rewrite Legalizer using RBLegalizeRules. Other way around is questionable, did not consider upgrading LegalityPredicate and LegalizeMutation to work with Register banks
