This PR allows using `#[repr(simd)]` on ADTs containing a single array field: ```rust #[repr(simd)] struct S0([f32; 4]); #[repr(simd)] struct S1<const N: usize>([f32; N]); #[repr(simd)] struct S2<T, const N: usize>([T; N]); ``` This should allow experimenting with portable packed SIMD abstractions on nightly that make use of const generics.
