Directly compute the cost of a VPlan after construction and track it
together with a plan. This allows moving selecting the best VF to the
planner. This seems to be a good fit anyways, and removes code from the
cost-model that is not directly related to assigning costs to a specific
plan/VF. Later this can be swapped out with computing the cost for a
plan directly.

This may help to simplify D142015 <https://reviews.llvm.org/D142015>.
