Incredibly powerful type system λλλ

The wasm ABI allows for a bit more flexibility than the C one.
I’m not sure how much impact it has on practice (probably very little, otherwise somebody would have fixed it), but in native code there’s a lot of potential for mismatching behaviors from the two different runtimes.
