    M llvm/test/Transforms/LoopVectorize/interleave-and-scalarize-only.ll

  Log Message:
  -----------
  [VPlan] Don't replace scalarizing recipe with VPWidenCastRecipe.

Don't replace a scalarizing recipe with a VPWidenCastRecipe. This would
introduce wide (vectorizing) recipes when interleaving only.
