When I say WIP, I really mean it. This has no comments, no nothing, but follows this <https://en.wikipedia.org/wiki/Reaching_definition> algorithm pretty literally.

This analysis isn't conservative enough yet, I really should include function calls with non-const references into the gen set, but hey, at this point I'm optimistic that it can be done.
