We should probably break this down and add statistics for each module using keys named "loadedDwoFileCount" and "dwoFileCount" in each module's statistics.  And then we still add totals at the end as you have. So maybe fetch into module_stat first and then update the totals:
```
UpdateDwoFileCounts(sym_file, module_stat.total_dwo_file_count,
                          module_stat.loaded_dwo_file_count);
total_dwo_file_count += module_stat.total_dwo_file_count;
total_loaded_dwo_file_count += module_stat.loaded_dwo_file_count;
```
We will need to add two things to ModuleStats:
```
uint32_t dwo_file_count = 0;
uint32_t loaded_dwo_file_count = 0;
```
