See faster-cpython/ideas#84
This appears to improve startup time by another 10% or more compared to main.

After PR 29118 is merged we get the benefits on UNIXy systems. We have several TODOs left then:
(Definitely:) Generate Windows build files
(Probably:) Find a way to avoid having to regenerate everything whenever any source file changes (any source file -> _bootstrap_python -> all generated files)
(Maybe:) Consider putting all generated code together in one file, for more savings (and build simplification)
