I have very briefly looked at the changes, which seem ok.  I will give a closer look soon.

However, there needs to be a change log, and I'd like to see some numbers on how much faster IPP makes these routines compared to either the SSE2 versions or the default versions.

Also, it might be better to review this after bug 77950 (sse2 for vsvesq and vmaxmgv) has been committed.
