Add rustc-codegen-cranelift component to rust-overlay for nightly

[benwis]

Apologies if there is some way to do this I'm missing, but I'm trying to add rustc-codegen-cranelift as a component, as it's included in the latest nightly. Since it's very new, I don't think it's included.

Can I get that added?

Enabling extensions = [ "rustc-codegen-cranelift" ] should work. But right now, there are some issues upstream that it contains only documentations but no backend DLL. See rust-lang/rust#81746 (comment). The next nightly release since rust-lang/rust#117328 should make it work.

2023-10-31 is out with the fix. Now this works under master:

rust-bin.nightly."2023-10-31".minimal.override {
  extensions = [ "rustc-codegen-cranelift-preview" ];
}

I verified that rustc -Zcodegen-backend=cranelift compiles and runs flawlessly. 🎉

Indeed it does, it works with just rustc-codegen-cranelift as well. Thanks for looking into it!
