Merge #1786
1786: Various minor trait improvements r=matklad a=flodiebold
- lower bounds on trait definition, i.e. super traits
- use super traits for associated types
- use traits from where clauses and their super traits for method resolution
- lower fn-like paths (i.e. `Fn(X, Y) -> Z`)
- pass the environment to Chalk in the correct way to make elaboration work, i.e. inferring things like `T: Clone` from `T: Copy`. The clauses need to be wrapped in `FromEnv` clauses for that to work, which I didn't do before.
- add some tests for closure inference already
