[x265] [PATCH 0/4] AArch64: Optimize and add pixel_var Implementations

[Li Zhang]

Hi,

This patch series optimizes the exisiting standard bit-depth pixel_var
Neon intrinsics implementation, deletes the slower assembly
implementation. It also adds Neon DotProd intrinsics implementation for
the standard bit-depth and Neon, SVE intrinsics implementations for the
high bit-depth of pixel_var function.

Many thanks,
Li
