A couple of naïve questions (I haven't checked):
Does it increase the alignment requirement?
If yes, should it be notified somewhere (API bump, comment in the
relevant header, ...)?

> x86inc.asm doesn't seem to handle cmpps or its aliases properly when using avx.

I remember fixing its declaration (missing one parameter) while
working on aac (maybe one year ago). It's unrelated, maybe?

Otherwise looks obvious.
