Unrolled build for rust-lang#126286

Rollup merge of rust-lang#126286 - nnethercote:fix-test-LL-CC, r=lqd

Make `storage-live.rs` robust against rustc internal changes.

Currently it can be made to fail by rearranging code within `compiler/rustc_mir_transform/src/lint.rs`.

This is a precursor to rust-lang#125443.

r? ```@lqd```
