    arm64: mc: Optimize mc_8tap_regular_w4_hv_8bpc for A53 · e80955cc

    Before:                       Cortex A53   Snapdragon 835
    mc_8tap_regular_w4_hv_8bpc_neon:   543.6   359.1
    After:
    mc_8tap_regular_w4_hv_8bpc_neon:   466.7   355.5
    
    The same kind of change doesn't seem to give any benefits on the 8
    pixel wide hv filtering though, potentially related to the fact that
    it uses not only smull/smlal but also smull2/smlal2.
