  Log Message:
  -----------
  [VPlan] Use skipCostComputation when pre-computing induction costs.

This ensures we skip any instructions identified to be ignored by the
legacy cost model as well. Fixes a divergence between legacy and
VPlan-based cost model.

Fixes https://github.com/llvm/llvm-project/issues/106417.
