[PATCH] D116123: [VPlan] Handle IV vector splat as VPInstruction.

[Florian Hahn via Phabricator via llvm-commits]

Address latest comments, thanks! The most notable changes are always generating VPWidenCanonicalIVRecipes and then try to replace them by either a vector induction or a step-vector in a separate VPlan-to-VPlan transform, if possible.
