Deal with unnormalized projections when structurally resolving types with new solver 1. Normalize types in `structurally_resolved_type` when the new solver is enabled 2. Normalize built-in autoderef targets in `Autoderef` when the new solver is enabled 3. Normalize-erasing-regions in `resolve_type` in writeback This is motivated by the UI test provided, which currently fails with: ``` error[E0609]: no field `x` on type `<usize as SliceIndex<[Foo]>>::Output` --> <source>:9:11 | 9 | xs[0].x = 1; | ^ ``` I'm pretty happy with the approach in (1.) and (2.) and think we'll inevitably need something like this in the long-term, but (3.) seems like a hack to me. It's a *lot* of work to add tons of new calls to every user of these typeck results though (mir build, late lints, etc). Happy to discuss further. r? `@lcnr` |
