Here's a proposal for this. I haven't strongly tested it (just ran
fate-aac without my other patches) because, in short, I can't at the
moment.

And for the wd unpacks, I guess there is probably too much shuffling
and shifting to do to add support for SSE1, as it kills opportunities
for better scheduling.
