$subj, 10% faster TwinVQ decoding.
As a side note, this option is not enabled even when passing
"-march=native -mtune=native" to GCC. A possible reason for it, quoting
the GCC doc, is "The resulting code should be considerably faster [...]
but may break some existing code that expects temporaries to be 80bit.".
