Ideally we would have a dedicated MachineRepresentation for Smis during representation selection and use that to properly optimize ObjectIsSmi (and other ObjectIs<Type> predicates), but that will take some time to get that done. So in the meantime we can just do simple (local) strength reduction on ObjectIsSmi to avoid Smi checks in the simplest cases at least.
