This reverts commit ceb9c8127f.
Reason for revert: Tanks compile time
Original change's description:
> [sfi] Remove SFI function literal id field
>
> SharedFunctionInfos store their original function literal's id. This is
> also their index in the Script's SFI list.
>
> Since the function literal id is only needed for lazy compilation and live
> edit, we can calculate it on-the-fly by linear search in the Script SFI list,
> and save a field on the SFI.
>
> If this regresses compile performance, we could alternatively store the
> function literal id on the preparsed scope data as future work.
