Can't infer Impl Into<T> types

[matklad]

fn foo(x: impl Into<i32>) {
    let x = x.into(); // no type hint here
    x.abs(); // unresolved method here
}

THis works with rustc though.

@flodiebold is this a dupe of some super-complicated issue? From the look of it, the example seems pretty obvious...

I think that's rust-lang/chalk#584 / #5514.

indeed! dupe of #5514
