    This reduces overhead and lets us use less branchy code for zigzag, dequant,
    decimate, and so on.
    Reorganize and optimize a lot of macroblock_encode using this new function.
    ~1-2% faster overall.
    
    Includes NEON and x86 versions of the new function.
    Using larger merged functions like this will also make wider SIMD, like
    AVX2, more effective.
