IIUC, the requirement for versioning generated sources is that some places
in the code generation rely on Sets, and so is not completely deterministic.
i.e. the same Slang code is not *guaranteed* to produce the same C code.
So the C code used to build the VM needs to be versioned to ensure
you can work backwards while debugging.
