   The motivation for the manual unrolling of the loops is so that LLVM does this for us. If you check the godbolt output linked in the PR you'll see it is using AVX2 instructions. This fits with what we've seen in general with the arrow compute kernels, where only AVX512 seems to need manual implementation.
