After this CL all liveedit tests call the same LiveEdit::PatchScript
method. This method will be updated later.
As well some new liveedit cctests added, unfortunately part of them
do not work with current implementation.

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.

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.

Previously, when restarting a frame, we would rewrite all frames
between the debugger activation and the frame to restart to squash
them, and replace the return address with that of a builtin to
leave that rewritten frame, and restart the function by calling it.
We now simply remember the frame to drop to, and upon returning
from the debugger, we check whether to drop the frame, load the
new FP, and restart the function.
