215e6bea - [LV] Use MapVector for ScalarCostsTy for deterministic iter order (NFC)

[LV] Use MapVector for ScalarCostsTy for deterministic iter order (NFC) We iterate over the scalar costs of instruction when printing costs, and currently the iteration order is not deterministic. Currently no tests check the output with multiple instructions in the map, but those will come soon.
