```
ReferenceProcessor::ReferenceProcessor(BoolObjectClosure* is_subject_to_discovery,
uint mt_processing_degree,
bool mt_discovery,
uint mt_discovery_degree,
bool concurrent_discovery,
BoolObjectClosure* is_alive_non_header)
```
`mt_discovery` is effectively `mt_discovery_degree > 1`, so one can drop `bool mt_discovery` in the arg list.
