Yes, VNNI intrinsic `vpdpbsud[,s], vpdpbssd[,s], vpdpbuud[,s], vpdpwssd, vpdpwuud, vpdpwsud, vpdpwssd` are suffering from the same type problem.

Only `vpdpbusd` and `vpdpbusds` are fixed because:
1. I want to make sure that I'm doing it correctly,
3. The size of this one MR might be too large if I updated all of them

Should I separate other intrinsic into a few MRs (maybe 2) to keep the size of each manageable?
