This removes a load per element when a repeated primitive field by avoiding a reload of RepeatedField<T>::rep_. This is also a data dependency for the subsequent (and remaining) load. For fixed-sized fields, this extends the changes to SerializeWithCachedSizes in 7f3e237 to SerializeWithCachedSizesToArray.
