Implement a few more goals. The subtype goal specifically is important, since it's required for this code to compile:

fn main() {
  let mut x = vec![];
  x.push(1i32);
}

(I think we emit a subtype goal here because of coercion).

Drive-by: Also implements --compare-mode=next-solver -- I've been using this locally a lot to find out what works and what doesn't. I'm also happy to split this out into another PR.
