Add a new PtrAdd opcode to VPInstruction that corresponds to IRBuilder::CreatePtrAdd, which creates a GEP with source element type i8. This is then used to model scalarizing VPWidenPointerInductionRecipe by introducing scalar-steps to model the index increment followed by a PtrAdd. Note that PtrAdd needs to be able to generate code for only the first lane or for all lanes. This may warrant introducing a separate recipe for scalarizing that can be created without relying on the underlying IR.
