This reverts commit ca20aab38465ce5d5990987337c57650350af1f6.

That commit causes generation of incorrect register names on
vm-noopt-simarm64-mac-be, and it seems to cause a disk full
error later on (making the bot purple).

Gardening: Talked to Slava, now reverting Ryan's CL because it causes generation
of wrong assembly code on Mac.

update the bots to avoid this.
