Rollup merge of rust-lang#125683 - Oneirical:patience-testing-test, r=jieyouxu Rewrite `suspicious-library`, `resolve-rename` and `incr-prev-body-beyond-eof` `run-make` tests in `rmake.rs` format Part of rust-lang#121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html). Some oddly specific ignore flags in `incr-prev-body-beyond-eof`: ```rs // ignore-none // ignore-nvptx64-nvidia-cuda ``` it could be interesting to run a try job, but it seems there is no nvidia-cuda in the CI settings (`jobs.yml`). try-job: armhf-gnu
