…ck, r=oli-obk Handle return-position `impl Trait` in traits properly in `register_hidden_type` The bounds that we get by calling `bound_explicit_item_bounds` from an RPITIT have projections, not opaques, but when we're *registering* an opaque, we want to treat it like an opaque. Coincidentally fixes rust-lang#102688 as well, which makes sense, since that was failing because we were inferring an opaque type to be equal to itself (opaque cycle error => "cannot resolve opaque type"). Fixes rust-lang#103352 r? `@oli-obk`
