  Log Message:
  -----------
  [LV][VPlan] Print VPlan after construction and initial optimizations. NFC (#187443)

This patch add a helper pass `printOptimizedVPlan` to print the plan at
the end of the VPlan construction and optimize pipeline.

This patch enables the opportunity that we can further clamp and attach
VF range after `VPlanTransforms::optimize` and not changing the test
printing (#172799).
