Great thanks. Besides the DbgInfoIntrinsics,  do we need some way to attach the debug metadata from the original instructions to the VPInstructions? I suppose initially we could get them from the underlying values, but IIUC some VPlan transformations could introduce new VPInstructions without underlying values.
