ad72da24 - [VPlan] Consider VPDerivedIV & VPScalarIVSteps for forced costs. (#222918)

[VPlan] Consider VPDerivedIV & VPScalarIVSteps for forced costs. (#222918) Now that we compute VPDerivedIV and VPScalarIVSteps costs directly in VPlan, also account for them with forced costs. They never have underlying instructions, so always add the forced cost for them. Previously they would have been accounted for in precomputeCosts. PR: https://github.com/llvm/llvm-project/pull/222918
