  Log Message:
  -----------
  [VPlan] Print VPValue operands for VPWidenPHI if possible.

For VPWidenPHIRecipes that model all incoming values as VPValue
operands, print those operands instead of printing the original PHI.

D99294 updates recipes of reduction PHIs to use the VPValue for the
incoming value from the loop backedge, making use of this new printing.
