Rollup merge of #130268 - RalfJung:simd-shuffle-idx-vector, r=compiler-errors 
simd_shuffle: require index argument to be a vector

Remove some codegen hacks by forcing the SIMD shuffle `index` argument to be a vector, which means (thanks to https://github.com/rust-lang/rust/pull/128537) that it will automatically be passed as an immediate in LLVM. The only special-casing we still have is for the extra sanity-checks we add that ensure that the indices are all in-bounds. (And the GCC backend needs to do a bunch of work since the Rust intrinsic is modeled after what LLVM expects, which seems to be quite different from what GCC expects.)

Fixes https://github.com/rust-lang/rust/issues/128738, see that issue for more context.
