Matt Turner 7d4beedc61 mmx: add and use pack_4x565 function 
The pack_4x565 makes use of the pack_4xpacked565 function which uses pmadd.

Some of the speed up is probably attributable to removing the artificial
serialization imposed by the
	vdest = pack_565 (..., vdest, 0);
	vdest = pack_565 (..., vdest, 1);
	...
pattern.
