Rollup merge of #128160 - compiler-errors:auto, r=jackh726
Don't ICE when auto trait has assoc ty in old solver Kinda a pointless change to make, but it's observable w/o the feature gate, so let's just fix it. I reintroduced this ICE when I removed the "auto impl" kind from `ImplSource` in #112687. Fixes #117829 Fixes #127746
