The serial mode's wave-end check threw when a unit changed a held function in place, even when the unit had no record and its change was its own lowering's: two functions that define computed-key properties on one class both rebuild the class's descriptor guard. Each unit's in-place changes are now checked against the names its IR and new entries quote: a unit with a record that changed such an entry has no record, and a unit without one keeps its changes. The wave-end check throws only for a change to an entry no unit names.
