1120: More trait infrastructure r=matklad a=flodiebold

This adds enough trait infrastructure to be able to make some deductions about type variables when resolving trait methods, while at the same time doing as little as possible that will be later replaced by Chalk 😄 

E.g. (as the tests show) if we have
```rust
trait Trait<T> { fn method(self) -> T }
impl Trait<u32> for S {}
...
S.method()
```
we can infer that the return type is `u32`. On the other hand the unification logic is so primitive that we can't handle e.g. `impl<T> Trait<T> for S<T>`.

It's all quite hacky, I plan to refactor the parts that will stay, while hopefully the other parts will be replaced soon 🙂 In particular, we need to handle 'containers' (impls and trait defs) more cleanly, and I need to reorganize the method resolution / type inference code...

a1ed53a4f1 More trait infrastructure 
- make it possible to get parent trait from method
 - add 'obligation' machinery for checking that a type implements a
   trait (and inferring facts about type variables from that)
 - handle type parameters of traits (to a certain degree)
 - improve the hacky implements check to cover enough cases to exercise the
   handling of traits with type parameters
 - basic canonicalization (will probably also be done by Chalk)
