2009-01-10	Add new tighter SSE2 unpremultiply.	M Joonas Pihlaja	2	-2/+107
	The same issues as with memcpy are now affecting SSE2 enabled unpremultiplication: the choice of movntd vs. movdqa vs. movdqu for writing to the destination buffer is crucial, but depends on how the result is used and what size it is. If it fits in L2 and is going to be used quickly, then it makes sense to use movdqa/dqu to write to the destination. If it's not going to be used or doesn't fit then it's far better to use movntdq.
