Auto merge of #114345 - lqd:revert-113588, r=RalfJung

Revert #113588 to fix bootstrap timings

This reverts #113588 which seems to have broken perf's bootstrap timings via some git issue

rust-lang/rust#114318 (comment) show a newly broken benchmark, the error at the time was

```
fatal: Path 'src/ci/channel' exists on disk, but not in 'e62323df22ecf9c163023132d17b7114f68b72e8'.
       thread 'main' panicked at 'command did not execute successfully: cd "/home/collector/rustc-perf/rust" && "git" "show" "e62323df22ecf9c163023132d17b7114f68b72e8:src/ci/channel"
       expected success, got: exit status: 128', config.rs:1786:27
```

If this lands, it will reopen #101907 and annoy miri, but it could actually be an issue that would appear during the next bootstrap bump, not just rustc-perf today.
