[LV] Determine NumPredStores before computing widening costs. (#199341) Determine NumPredStores before computing widening costs, so we consistently apply large predicated store cost to all stores, matching the VPlan cost model. In practice that should not impact vectorization decisions, as the huge cost for any predicated store other than the first already effectively disables vectorization.
