nit: you can also replace two instances in freeze_intrinsics.js:

Can you open a separate PR for this?

freeze_intrinsics.js is executed before any user code, I don't think it's worth adding it to the primordials object: there's no security reason to do so, IMHO we should fix frozen_intrinsics.js code instead.
