Auto merge of #97472 - cuviper:rebase-rustc-rayon, r=Mark-Simulacrum

Update to rebased rustc-rayon 0.4

In rayon-rs/rayon#938, miri uncovered a race in `rustc-rayon-core` that had already been fixed in the regular `rayon-core`. I have now rebased that fork onto the latest rayon branch, and published as 0.4. I also updated `indexmap` to bump the dependency.

`Cargo.lock` changes:

    Updating indexmap v1.8.0 -> v1.8.2
    Updating rayon v1.5.1 -> v1.5.3
    Updating rayon-core v1.9.1 -> v1.9.3
    Updating rustc-rayon v0.3.2 -> v0.4.0
    Updating rustc-rayon-core v0.3.2 -> v0.4.1
