Generate vmovsh instead of vpblendw for specific vec_merge.
On SPR, vmovsh can be execute on 3 ports, vpblendw can only be
executed on 2 ports.
On znver4, vpblendw can be executed on 4 ports, if vmovsh is similar
as vmovss, then it can also be executed on 4 ports.
So there's no difference for znver? but vmovsh is more optimized on
SPR.
