Support repr(simd) on ADTs containing a single array field This is a squash and rebase of `@gnzlbg's` #63531 I've never actually written code in the compiler before so just fumbled my way around until it would build 😅 I imagine there'll be some work we need to do in `rustc_codegen_cranelift` too for this now, but might need some input from `@bjorn3` to know what that is. cc `@rust-lang/project-portable-simd` ----- 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. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
