    M llvm/test/Transforms/LoopVectorize/X86/induction-costs.ll

  Log Message:
  -----------
  [LV] Include chains feeding inductions in cost precomputation.

Include chain of ops feeding inductions in cost precomputation for
inductions, not just the induction increment. In VPlan, those
instructions will be cleaned up, as both phi and increment are generated
by VPWidenIntOrFpInductionRecipe independently.

Fixes https://github.com/llvm/llvm-project/issues/101337.
