Craig Topper 4561edbec0 [X86] Add X86ISD::VMFPROUND to handle the masked case of VCVTPD2PSZ128 which only produces 2 result elements and zeroes the upper elements.
We can't represent this properly with vselect like we normally do. We also have to update the instruction definition to use a VK2WM mask instead of VK4WM to represent this.

Fixes another case from PR34877.
