This patch rewrites known-size calls to memclrNoHeapPointers with an OpZero. This significantly improves performance and lets some clears get DSE'd. One of the cases where this applies is zeroing a known-size array, example: var x [256]int8 ... for a := range x { x[a] = 0 } Other cases can be found in the runtime itself where memclrNoHeapPointers is sometimes directly invoked with a constant. It seems that for some sized-clears on some architectures (AMD64, maybe others) the memcrlNoHeapPointers is more performant than OpZero. See the issue #56997 for more details.
