[x265] [PATCH 0/8] AArch64: Clean up and optimize block copy primitives

[Li Zhang]

Hello,

This patch series optimizes and implements several AArch64 block copy
primitives using Neon intrinsics. It also cleans up and removes the Neon
and SVE assembly implementations that are either slower or offer no
performance benefit.

Many thanks,
Li
