So now that VPDerivedIVRecipe simply mirrors the type of its first start-value operand, should it join VPCanonicalIVPHIRecipe et al.'s or VPPredInstPHIRecipe et al.'s cases above and remove its getScalarType() method? Possibly as a follow-up.

Should VPWidenIntOrFpInductionRecipe's trunc also utilize VPScalarCastRecipe, and retire its getScalarType(), possibly as a follow-up?
