31711c90 - [VPlan] Only apply forced cost to recipes with underlying values. (#168372)

[VPlan] Only apply forced cost to recipes with underlying values. (#168372) Only apply forced instruction costs to recipes with underlying values to match the legacy cost model. A VPlan may have a number of additional VPInstructions without underlying values that are not considered for its cost, and assigning forced costs to them would incorrectly inflate its cost. This fixes a cost divergence between legacy and VPlan-based cost models with forced instruction costs. PR: https://github.com/llvm/llvm-project/pull/168372
