Switch tests from using `-debug[-only=LoopVectorize]` to `-vplan-print-after` as that provides better control at what step in the pipeline we want to check the VPlan (I'm using `optimize$` for now to preserve previous state). Then, update `-vplan-print-after*` to print what function the loop belongs to. That enables us to simplify VPlan UTC support as the output of the updated tests contains the VPlan dump only - no special filtering/extraction is necessary anymore.
