SILGen: Consume materializes used for writeback.
Split CleanupMaterialize into CleanupMaterializeAlloc and CleanupMaterializeValue. Have emitMaterialize, emitGetProperty, and other methods that create materialize buffers return a new Materialize type, which has a consume() method to disable the CleanupMaterializeValue cleanup, load the value, and return it as a ManagedValue for the caller to consume.
