Right now, we only support rewriting &self and &mut self into &dyn MyTrait and &mut dyn MyTrait. This expands it to handle the full gamut of receivers by calculating the receiver based on substitution rather than based on a rewrite. This means that, for example, Arc<Self> will become Arc<dyn MyTrait> appropriately with this change.
This approach also allows us to support associated type constraints as well, so we will correctly rewrite &self into &dyn MyTrait<T=i32>, for example.
