  Log Message:
  -----------
  [VPlan] Update VPWidenMemoryInstruction to not inherit from VPValue.

VPWidenMemoryInstruction also models stores which may not produce a value.
This can trip over analyses. Improve the modeling by only adding
VPValues for VPWidenMemoryInstructionRecipes modeling loads.
