    Original issue's description:
    > [turbofan] Add support for copy-on-write element stores.
    >
    > This extends JSNativeContextSpecialization with support for stores to
    > fast object/smi element backing stores that are marked as copy-on-write.
    > In this case we first call the CopyFixedArray builtin to take a copy of
    > the elements backing store, and then store the new elements back to the
    > object, and finally perform the actual element store.
