Summary: In rL299692 I improved strip-dead-debug-info's ability to drop CUs that are not referenced from the current module. However, in doing so I neglected to realize that some SPs could be referenced entirely from inlined functions. It appears I was not the only one to make this mistake, because DebugInfoFinder, doesn't find those SPs either. Fix this in DebugInfoFinder and then use that to make sure not to drop those CUs in strip-dead-debug-info.
