Oli Scherer 40d5609548 Make DefiningAnchor::Bind only store the opaque types that may be constrained, instead of the current infcx root item.
This makes `Bind` almost always be empty, so we can start forwarding it to queries, allowing us to remove `Bubble` entirely

found struct `std::option::IntoIter<_>`
note: this item must have the opaque type in its signature in order to be able to register hidden types
