I don't really see any advantage of adding intrinsics to FFMpeg so I'm
against it.

Standardizing the x86 assembly in one "language" is preferable for
multiple reasons, especially since yasm/nasm + x86inc is more
powerful/flexible (better macro support etc.) than using intrinsics.

If you know how to write intrinsics it shouldn't be that much of a
learning curve to become familiar with yasm/nasm + x86inc either, and
you can always drop by on IRC to ask questions.
