patch to improve AES-NI performance

[Ollivier Robert]

According to Ollivier Robert:
> You are right, I wanted to say r226837 which is the "code" one.

FYI I've finally merged r226837,r226839 as r254856 in stable/9 as it is a prerequesite to apply jmg's patch.  I've asked re@ whether they would consider this for 9.2.  It is very late in the 9.2 release circle but that patch has been in 10 for more than a year now...
