[issue45696] "Deep-freeze": skip the marshal step by generating C code

[Guido van Rossum]

Guido van Rossum  added the comment:

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)

New submission from Guido van Rossum :

See https://github.com/faster-cpython/ideas/issues/84

This appears to improve startup time by another 10% or more compared to main.
