Description
cc @rust-lang/clippy @RalfJung
cc @rust-lang/compiler @rust-lang/infra we gate on clippy soon, so if you break clippy you need to fix it immediately in the same PR. This is trivial now though, since we are basically in a monorepo state, so you just edit stuff in src/tools/clippy/ until everything works again.
Synchronizations of the remote repo and the local subtree is explained in CONTRIBUTING.md
The first port (clippy) is being done in #70655
