Fix Clippy lints

[GabrielMajeri]

This PR attempts to get CI to work again by fixing Clippy lints.

[GabrielMajeri]

It seems it still doesn't build currently because of the core_simd dependency

[gnzlbg]

I see :/

Core_arch was fixed recently but there is no new version yet, you could try patching Cargo.toml to use git version.

[GabrielMajeri]

Well this is just lovely. While trying to still fix the build I managed to get an ICE...

error: internal compiler error: src/librustc_mir/transform/qualify_consts.rs:1145: promotion candidate validation mismatches (see above)

I think it's going to take a while until we get CI working again...

[mati865]

There are no reports of this ICE in Rust repo. Can you temporary add RUST_BACKTRACE=1 to the CI job and report it upstream?

[ecstatic-morse]

@GabrielMajeri rust-lang/rust#66016 should be fixed in the next nightly release. Thanks for reporting this BTW.

[mati865]

Clippy is green now, probably core_arch needs new release.

This looks lovely! I know you wanted to fix CI with this but this looks like it fixes everything that is still blocking #292 so I'm going to merge it.
