Break up compcore.re

[peblair]

compcore.re is ~3500 lines now, and it is responsible for basically all of the mashtree->binaryen compilation logic. Is there a way we can break this up into more manageable chunks? It's not obvious to me where we can carve things up. Where would make the most sense?

It looks like this is a duplicate of #85 🙂

But yes. We did some work to break it up a bit but it needs a lot more work... Maybe moving the allocation stuff into its own file, grouping some constructs, stuff like functions maybe.

Oops. I'll close this one as a duplicate.
