2025-03-31gccrs: fix unconstrained infer vars on generic associated typePhilip Herron3-10/+9
The trick here is that when Bar::test is resolved it resolves to the trait method: fn <Bar<i32>, T> (placeholder) -> placeholder Which is fine so we need to setup the associated types for Bar<i32> which means looking up the associated impl block then setting up the projection of A = T so it becomes: fn <Bar<i32>, T> (placeholder: projection<T>:T) -> placeholder: projection<T>:T But previously it was auto injecting inference variables so it became: fn <Bar<i32>, T> (placeholder: projection<T>:?T) -> placeholder: projection<T>:?T The issue is that the binding of the generics was still T so this caused inference variables to be injected again but unlinked. A possible tweak would be that we are substituting again with new infer vars to actually just unify them enplace so they are all part of the chain. This still might be needed but lets hold off for now. So basically when we are Path probing we dont allow GAT's to generate new inference vars because they wont be bound to this current segment which just causes confusion.

2025-03-24gccrs: support generic super traits recursivelyPhilip Herron9-60/+114
In order to handle generic super traits on any trait bound we need to ensure we track the TypeBoundPredicate as part of the TraitReference instead of just the raw TraitReferences because these will have any applied generics enplace. Then for any TypeBoundPredicate it takes a copy of the super traits because this is the usage of a TraitBound and we can apply generics which then need to be recursively applied up the chain of super predicates. The main tweak is around TypeBoundPredicate::lookup_associated_item because we need to associate the predicate with the item we are looking up so the caller can respect the generics correctly as well.
