[AArch64] Optimize ScaleRowDown38_3_Box_NEON Replace LD4 and TRN instructions with LD1s and TBL since LD4 is known to be slow on some micro-architectures, and remove other unnecessary permutes. Reduction in run times: Cortex-A55: -24.8% Cortex-A510: -32.7% Cortex-A520: -37.7% Cortex-A76: -51.8% Cortex-A715: -58.9% Cortex-A720: -58.9% Cortex-X1: -54.8% Cortex-X2: -50.3% Cortex-X3: -57.1% Cortex-X4: -49.8% Cortex-X925: -52.0% Co-authored-by: Cosmina Dunca <cosmina.dunca@arm.com> Bug: b/42280945 Change-Id: Ie96bac30fffbe41f8d1501ee289795830ab127e5 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5872803 Reviewed-by: Frank Barchard <fbarchard@chromium.org> Reviewed-by: Justin Green <greenjustin@google.com>
