A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/1996963002/ by jkummerow@chromium.org.

The reason for reverting is: This array only contains Smis, see its only store
site five lines above:

array->set(array_size++, Smi::FromInt(i));

If you want to improve something here, use a C++ array instead of a FixedArray.
There's no reason to have this short-lived list on the V8 heap..
