- Removed a default value in `emitSourceRegions()`, added the corresponding argument to its call in `EmptyCoverageMappingBuilder::write()`.
- Removed an additional sorting step in `CounterCoverageMappingBuilder::write()`, the patch is now depends on the extended sorting creteria in `CoverageMappingWriter::write()`, see https://reviews.llvm.org/D24034.
