Reason for revert: breaks gcc build
Original change's description:
> [runtime] Make JSFunction::prototype_or_initial_map field optional.
>
> Functions that don't have prototype need to store neither prototype nor
> initial map, so the |prototype_or_initial_map| field is not required for
> such maps.
>
> Bug: v8:6459
