Unrolled build for rust-lang#137262

rust-timer · web-flow · commit 7c9185c3791a · 2025-02-20T00:59:23.000-05:00
Rollup merge of rust-lang#137262 - compiler-errors:ast-ir-begone, r=lcnr Make fewer crates depend on `rustc_ast_ir` I think it simplifies the crate graph and also exposes people less to confusion if downstream crates don't interact with `rustc_ast_ir` directly and instead just use its functionality reexported through more familiar paths. r? oli-obk since you introduced ast-ir
