This has been unstable since it was first introduced in
https://github.com/rust-lang/rust-clippy/pull/5363. In that time, I have
been using it successfully in nightly without issues. I don't think
there are any blocking issues now that RUSTC_WORKSPACE_WRAPPER is
stabilized, so this can be stabilized.
This will terminate the program if run via "cargo run".
"cargo run" does currently not work because at least a bunch of paths do not take that into account.
