    Original change's description:
    > [ic] Improve performance of KeyedStoreIC on literal-based arrays.
    > 
    > In mode STORE_AND_GROW_NO_TRANSITION, the handler for elements stores
    > used to bail out when seeing a COW array, even if the store that
    > installed the handler had been operating on the very same array.
    > 
    > This CL adds support for COW arrays to the mode (and renames it to
    > STORE_AND_GROW_NO_TRANSITION_HANDLE_COW).
