  -----------
  [VPlan] Materialize VF and VFxUF using VPInstructions. (#152879)

Materialize VF and VFxUF computation using VPInstruction
instead of directly creating IR.

This is one of the last few steps needed to model the full vector
skeleton in VPlan.

This is mostly NFC, although in some cases we remove some unused
computations.
