Would adding#[used] when creating this static work?

+1, if it's possible we should rely on regular user-available attributes instead of hardcoding stuff in the compiler, both for dead code and symbol export analysis.

I am not sure it will work (don't want to spend the time testing it with #104860), but it seems like a good idea anyway, done.

Interaction between dead code lint and #[used] attribute is tested in issue-41628.rs.

This would have avoided a bug in rust-lang#104860. In practice this shouldn't matter since nothing uses the query other than the `dead_code` lint, but this isn't documented as an internal-only query so it seems nice for it to be accurate. I think for `dead_code` it doesn't matter because the relevant code is generated by `rustc_builtin_macros` and isn't linted.
