This patches changes the safe_globals internal module into a
script that gets run during bootstrap and saves JavaScript builtins
(primordials) into an object that is available for all other builtin
modules to access lexically later.

can you add a test demonstrating that modifying Object.defineProperty or something doesn't break internal code?

Adding them to the bootstrap seems fine, but we still cannot use methods via . if we are wanting to have the original function.

@devsnek Do you have a good API to test this in mind? This test would depend on the implementation details of the API and if the API being tested is changed we would have to look for another one that uses these globals after user code execution starts. Or is there already any tests for the previous safe_globals? That would probably be enough to demonstrate this.
