[AArch64] Unroll to use full vectors in ARGBToARGB1555Row_NEON By loading packed 16-bit AR/GB data and operating on that directly we avoid the need to perform a separate widening step before the conversion. Reduction in runtime observed compared to the existing Neon code: Cortex-A55: -13.2% Cortex-A510: -5.4% Cortex-A76: -21.5% Cortex-A720: -25.2% Cortex-X1: -50.6% Cortex-X2: -36.8% Bug: b/42280945 Change-Id: I780c71fdff1d017464c6e4e38f86979dda0e43ad Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5790973 Reviewed-by: Frank Barchard <fbarchard@chromium.org> Reviewed-by: Justin Green <greenjustin@google.com>
