bors 9136560d32 Auto merge of #115933 - oli-obk:simd_shuffle_const, r=workingjubilee

Prototype using const generic for simd_shuffle IDX array

cc https://github.com/rust-lang/rust/issues/85229

r? `@workingjubilee` on the design

TLDR: there is now a `fn simd_shuffle_generic<T, U, const IDX: &'static [u32]>(x: T, y: T) -> U;` intrinsic that allows replacing

```rust
simd_shuffle(a, b, const { stuff })
```

with

```rust
simd_shuffle_generic::<_, _, {&stuff}>(a, b)
```

which makes the compiler implementations much simpler, if we manage to at some point eliminate `simd_shuffle`.

There are some issues with this today though (can't do math without bubbling it up in the generic arguments). With this change, we can start porting the simple cases and get better data on the others.

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.
