[PATCH] D120827: [VPlan] Helper to check if a recipe only uses scalar values of op.

[Ayal Zaks via Phabricator via llvm-commits]

Ayal added a comment.

How about VPScalarIVStepsRecipe, VPBlendRecipe, VPBranchOnMaskRecipe, VPPredInstPHIRecipe?

Is it worth distinguishing between recipes that can immediately tell they only use scalars (or only use first scalar lane) such as VPRepilcateRecipe - and those that don't care and need to check if all their users are of the former type, such as VPBlendRecipe and possibly VPPredInstPHIRecipe?
