Register normalization obligations instead of immediately normalizing in opaque type instantiation For lazy TAIT we will need to instantiate opaque types from within `rustc_infer`, which cannot invoke normalization methods (they are in `rustc_trait_resolution`). So before we move the logic over to `rustc_infer`, we need make sure no normalization happens anymore. This PR resolves that by just registering normalization obligations and continuing. This PR is best reviewed commit by commit I also included f7ad36e which is just an independent cleanup that touches the same code and reduces diagnostics noise a bit r? `@nikomatsakis` cc `@spastorino` |
