Rollup merge of #129383 - cjgillot:opaque-noremap, r=compiler-errors,petrochenkov
Remap impl-trait lifetimes on HIR instead of AST lowering Current AST->HIR lowering goes out of its way to remap lifetimes for opaque types. This is complicated and leaks into upstream and downstream code. This PR stops trying to be clever during lowering, and prefers to do this remapping during the HIR->ty lowering. The remapping computation easily fits into the bound var resolution code. Its result can be used in by `generics_of` and `hir_ty_lowering::new_opaque` to add the proper parameters and arguments. See an example on the doc for query `opaque_captured_lifetimes`. Based on https://github.com/rust-lang/rust/pull/129244/ Fixes https://github.com/rust-lang/rust/issues/125249 Fixes https://github.com/rust-lang/rust/issues/126850 cc `@compiler-errors` `@spastorino` r? `@petrochenkov`
