Implement some more predicates in the new solver
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.
