Hi Vladimir,

Thanks for your review.

> What about SubV* and MulV* nodes?

After checking commut_op_list, I think MulV*, AndV, OrV and XorV nodes
can also be added. Should I add them all?

SubV* nodes are not commutative, so I don't think they need to be
considered here.

> I prefer shared code change but we would need to test on all platforms which support vectors.
Yeah, we need to test on all platforms. We already tested previous
patch on x86 and aarch64 platforms, but we don't have other platforms.
