it doesn't look like if it will be removed anytime soon but when it is 
the case we should move it somewhere else.

I haven't checked how much of the mmx defines we are actually using (it 
is included mainly in filters and osd blending in libmythtv). If it is 
only marginally used I tend to agree that plain asm would be cleaner. If 
they are used extensively it's probably not worth the effort of replaing 
it.
