Immortalize/defer all functions in `__builtins__`

[Fidget-Spinner]

Feature or enhancement

Proposal:

We should immortalize all functions in the builtins module. This has benefits for the JIT, and will move the default build closer to the FT build.

Has this already been discussed elsewhere?

I have already discussed this feature proposal on Discourse
