revert r62655 for r63763

r63655 was tightly coupled to handle_frames and some assumptions seems
to have been broken by r63763.

To partially resolve Bug#14892, this reverts the optimization for now. I
want to make MJIT CI happy first and then I'll probably retry r63655 by
partially reverting r63763 for sp changes.

The skipped test is not fixed yet.
