Similar to other patches like D84680 <https://reviews.llvm.org/D84680>, this makes VPWidenRecipe a VPValue. Because of the way it interacts with the reduction code it also slightly alters the way that VPValues are registers, removing the up front NeedDef and using getOrAddVPValue to create them on-demand if needed instead.
