The proper attribute was added to `simd_shuffle*` in rust-lang/stdarch#825. This caused `promote_consts` to double-count its second argument when recording promotion candidates, which caused the promotion candidate compatibility check to fail.

Don't double-count `simd_shuffle` promotion candidates Resolves rust-lang#66016. The `#[rustc_args_required_const]` attribute was added to `simd_shuffle*` in rust-lang/stdarch#825. This caused `promote_consts` to double-count its second argument when recording promotion candidates, which caused the promotion candidate compatibility check to fail. Once `stdarch` is updated in-tree to include rust-lang/stdarch#825, all special logic around `simd_shuffle` can and should be removed.
