  Log Message:
  -----------
  [VPlan] Skip cost verification for loops with EVL gather/scatter.

The VPlan-based cost model use vp_gather/vp_scatter for gather/scatter
costs, which is different to the legacy cost model and cannot be matched
there. Don't verify the costs match for plans containing gather/scatters
with EVL.
