Revert of Debugger: use list to find shared function info in a script. (patchset #2 id:20001 of https://codereview.chromium.org/1206573004/)

Reason for revert:
[Sheriff] Breaks layout tests:

Original issue's description:
Debugger: use list to find shared function info in a script.

Now that we keep tabs on shared function infos from a script, we can speed up finding shared function infos for debugging. However, in case we have to compile a function that cannot be lazily compiled without context, we fall back to the slow heap iteration.
