getLegacyCost()

InstructionCost VPCostContext::getLegacyCost	(	Instruction *	UI,
		ElementCount	VF
	)		const

Return the cost for UI with VF using the legacy cost model as fallback until computing the cost of all recipes migrates to VPlan.

skipCostComputation()

bool VPCostContext::skipCostComputation	(	Instruction *	UI,
		bool	IsVector
	)		const

Return true if the cost for UI shouldn't be computed, e.g.

because it has already been pre-computed.
