Merge #1757
1757: Assoc type bindings r=flodiebold a=flodiebold
This adds support for type bindings (bounds like `where T: Iterator<Item = u32>`).
It doesn't yet work in as many situations as I'd like because of some [Chalk problems](https://github.com/rust-lang/chalk/issues/234). But it works in some situations, and will at least not bitrot this way ;)
(part of the problem is that we use `Normalize` to normalize associated types, but produce `ProjectionEq` goals from where clauses, so Chalk can't normalize using the environment; this would be fixed by using `ProjectionEq` for normalization, which I think is the 'proper' way, but then we'd run into those ambiguity problems everywhere...)
