1212e59bee Fix assertion error in unification (hopefully)
Currently, all types that we handle during inference need to be resolved as far
as possible at the time. It's maybe too brittle of an invariant; I need to think
how we can do this better. This should fix #484 though, I hope (if
it's the same case as I managed to reproduce).

7b0eaef580 Implement type inference for more binary operators
Mostly just for primitive numeric types such as u32 and f64. Not
yet a general solution using trait resolution.

there are only the data files).

etc. :)

cfa1de72eb Implement type variables
This will really become necessary when we implement generics, but even now, it
allows us to reason 'backwards' to infer types of expressions that we didn't
understand for some reason.

We use ena, the union-find implementation extracted from rustc, to keep track of
type variables.
