What do you mean by duplicated? That tables for 10 and 12 are?

Otherwise, I'm leaving the ssse3/opt parameter for 2 reasons:
- try to not perform changes that aren't required for it to work
- I don't know how the avx2 code would look but indeed, if it had to
use other tables, it would then use new macro(s)

Maybe your suggestions could be delayed after the code is converted to
ssse3? Probably there wouldn't be any, but patch conflicts would be
