[LV] Return Invalid from getLegacyCost when instruction cost forced. (#154543)
LoopVectorizationCostModel::expectedCost will only override the cost
returned by getInstructionCost when valid. This patch ensures we do
the same in VPCostContext::getLegacyCost, avoiding the "VPlan cost
model and legacy cost model disagreed" assert in the included test.
