It should be very rare in practice to happen; people would need to both have download-ci-llvm disabled and download-rustc enabled. I think it may be more common if we start turning this on by default, though.

Helps with #81930.

Before:

downloading https://ci-artifacts.rust-lang.org/rustc-builds/bf5cad8e775fb326465e5c1b98693e5d259da156/rust-std-nightly-x86_64-unknown-linux-gnu.tar.xz
curl: (22) The requested URL returned error: 404

After:

downloading https://ci-artifacts.rust-lang.org/rustc-builds/bf5cad8e775fb326465e5c1b98693e5d259da156/rust-std-nightly-x86_64-unknown-linux-gnu.tar.xz
curl: (22) The requested URL returned error: 404

error: failed to download pre-built rustc from CI

note: old builds get deleted after a certain time
help: if trying to compile an old commit of rustc, disable `download-rustc` in config.toml:

[rust]
download-rustc = false
