This PR makes compilation deterministic (by switching to fxhash) and improves the CLI.
Technically, the
std-based hash tables cannot be guaranteed to have the deterministic iteration order that we need, regardless of what hash you use, so I've added some micro-tests for the property that we need. I'm not optimistic about getting better guarantees fromstd, but I'll try.The CLI has also changed.
