Apparently enough for a small vendor like Intel to propose such things 
as orps, andps, andnps, and xorps.
So, that's what i feared... it was intentional. And now i guess the only 
sanctioned access to those ops is via builtins/intrinsics. Great.
If only i could get the same quality of code when using intrinsics to 
begin with...
