Merge #2567
2567: Handle impl Trait more correctly r=flodiebold a=flodiebold
When calling a function, argument-position impl Trait is transparent; same for return-position impl Trait when inside the function.
So in these cases, we need to represent that type not by `Ty::Opaque`, but by a type variable that can be unified with whatever flows into there.
