  [LV] Fix missing precomptueCosts() in emitInvalidCostRemarks(). (#114918)

We should always update the `SkipComputation` which is set in
`VPCostContext` before VPlan compute costs.

This patch prevent the assertion of in-loop reduction in the
`VPReductionRecipe::computeCost()` and other potential assertions of
partially implemented VPlan-based cost model.
