Support repr(simd) on ADTs containing a single array field #63531

Commits on Aug 13, 2019

  1. Support repr(simd) on ADTs containing a single array field 

    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.
