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 commit introduces VPValues for VPBlendRecipe to use as the values to blend. The recipe is generated with VPValues wrapping the phi's incoming values of the scalar phi. This reduces ingredient def-use usage by ILV as a step towards full VPlan-based def-use relations.
