[AArch64] Unroll ScaleRowDown4_NEON We can use wider load/store instructions here which is mostly an improvement across the board. Reduction in runtimes observed compared to the existing Neon implementation: Cortex-A55: +4.9% (!) Cortex-A510: -46.3% Cortex-A520: -49.0% Cortex-A76: -12.2% Cortex-A715: -15.5% Cortex-A720: -15.0% Cortex-X1: -12.4% Cortex-X2: -12.5% Cortex-X3: -12.3% Cortex-X4: +0.3% Bug: b/42280945 Change-Id: Id8af6499c63919924c2a954dfe7765b703ce4820 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5785970 Reviewed-by: Frank Barchard <fbarchard@chromium.org>
