> I am seeing 5-10% speedups when vectorizing `quant_4x4`. After runtime check generation, there's still another issue though (conditional load that's not hoisted out).

Hi @fhahn, I tried cherry-picking this patch and I'm not seeing `quant_4x4` getting vectorized. Maybe I'm missing something here. The commandline invocation I'm using is
`clang --target=aarch64-linux-gnu -mllvm -slp-memory-versioning -mllvm -debug-only=SLP -O3 -c quant_4x4.c -S -o quant_4x4.S`
