The benchmark CI regression is quite significant:

                          confidence improvement accuracy (*)   (**)  (***)
misc/freelist.js n=100000        ***    -73.53 %       ±1.13% ±1.52% ±2.01%

freelist is simple data structure, so refactoring to primordials causes a significant performance regression. I tried some solutions, but they didn't work. Do you all have any ideas about this issue? @aduh95
