Original change's description:
> [turbofan] Implement lowering of {JSCreateClosure}.
>
> This adds support for inline allocation of {JSFunction} objects as part
> of closures instantiation for {JSCreateClosure} nodes. The lowering is
> limited to instantiation sites which have already seen more than one
> previous instantiation, this avoids the need to increment the respective
> counter.
