[PATCH] D69471: [Coverage] Revise format to reduce binary size

Sorry for the delay here. An update: I tested this patch with a sanitized build on a Linux install, but could not reproduce the "malformed coverage data" errors seen on the Windows bots. At this point, it seems likely that there is a bug in CoverageMappingReader (this would explain why the .covmapping testing bundles fail to parse), and it may be that there is a separate issue on the producer side (this could explain why the 'instrprof-merging.cpp' test from `check-profile` failed). I think I need a Windows set up to debug further, and will try to find one. Meanwhile, if anyone has the bandwidth to attempt to reproduce on Windows, and to share a backtrace from where the `CoverageMapError` constructor is called, I would greatly appreciate it.
