Original change's description:
> [CloneObjectIC] overwrite monomorphic/polymorphic feedback if deprecated
>
> An object with a deprecated Map which has already been cached in
> CloneObjectIC feedback is still a valid Map for fast cloning --- but
> to be consistent with other ICs, deprecated maps are ignored, and are
> expected to be transitioned away from.
>
> If the source object has a deprecated map, the instance is migrated.
