Thanks for your comments @nemanjai 
I posted a new patch https://reviews.llvm.org/D106555 based on your codes for the splat loads. In that patch, more types will be handled.

I will leave this as an improvement for scalar_to_vector without a splat user. Not sure the improvement for `unadjusted_lxvwsx` is a motivated case. I don't see the improvement in https://reviews.llvm.org/D106555.
