s390x: use llvm intrinsics instead of simd_fmin/fmax

…duce-min-max aarch64: use `simd_reduce_{min, max}` on integers

s390x: add f64 tests for vec_min

ci is showing a lot of warnings (72) right now. apparently actions/checkout@v4 uses Node.js 20, and all github actions are scheduled to be force opted-in to Node.js 24 on 2026-06-02. I don't anticipate bumping the checkout action to v6 / Node.js 24 to cause any issues (Node.js 24 drops support for ARM32 and macOS versions <= 13.4, but this shouldn't matter because we use Docker to test in those environments, not github runners natively) but if it does cause issues it's probably better to find out now rather than by surprise 3 months from now... :)

ci: update to actions/checkout@v6

add ACLE random number generation intrinsics

stdarch is developed in its own repository. If possible, consider making this change to rust-lang/stdarch instead.

in rust-lang@a24022a we changed the argument types to be more accurate, and now the miri asserts on the simd type/size need to reflect that
