CR for RFR 8178800

[Vladimir Kozlov]

Hi Michael,

Why do you need pshufd()?

Why to save xmm0 in register you can use movdqu() but for stack you use 
evmovdqul()?

Why you can use movss(src, nds) and movsd(src, nds) when other 
instructions use evmovdqul() for that?

Why you removed (nds_enc < 16) block?

Thanks,
Vladimir
