original message:
Add Neon implementations of MCIF simdFilter{4,8}xX_N8 (#444)
Mostly a copy of the existing approach for simdFilter16xX_N8_neon.
Also rename the helper functions used by the existing
simdFilter16xX_N8_neon kernel to avoid name clashes with the new two
kernels introduced by this commit.
Running a video encoding job on a Neoverse V2 machine using the
--preset=fast setting shows a ~1.5% improvement in reported FPS.
