Do a bit more when sort_remaining_classes
Do a bit more when sort_remaining_classes

Summary:
This enables sorting of a few more sections of unordered classes, improving *compressed* APK size:
- The unordered rest of the primary dex
- The classes omitted from the original cold-start set (not seen in practice)
- "Additional classes" (just one in practice, the switch-inline dispatcher)
- The remaining classes in the first dex that is shared with the last chunk of ordered cold-start classes
