The sink-after and interleave-group vectorization decisions were so far applied to VPlan during initial VPlan construction, which complicates VPlan construction – also because of
their inter-dependence.
This patch refactors buildVPlanWithRecipes() to construct a simpler initial VPlan and later apply both these vectorization decisions, in order, as VPlan-to-VPlan
transformations.
