InnerLoopVectorizer's code called during VPlan execution still relies on original IR's def-use relations to decide which vector code to generate,
limiting VPlan transformations ability to modify def-use relations and still have ILV generate the vector code.
This patch introduces a VPValue for VPWidenMemoryInstructionRecipe to use as the stored value. The recipe is generated with a VPValue wrapping the stored value of the scalar store.
This reduces ingredient def-use usage by ILV as a step towards full VPlan-based def-use relations.
