arm64: mc: NEON implementation of avg/mask/w_avg for 16 bpc
Also ping @janne
The first commit adds some sort of macroing for adding BITDEPTH into the function name - I presume that probably should be added to some common header instead of adding it into the individual init file like here, and the second commit adds some sort of predecent for naming the 16 bpc assembly files (in this case I chose mc_16bpc.S
in addition to the existing mc.S
) - I'm open for opinions on this (in addition to normal review of the asm of course).
