DWARFCompileUnit * DWARFUnit::GetSkeletonUnit ( )

Get the skeleton compile unit for a DWO file.

We need to keep track of the skeleton compile unit for a DWO file so we can access it. Sometimes this value is cached when the skeleton compile unit is first parsed, but if a .dwp file parses all of the DWARFUnits in the file, the skeleton compile unit might not have been parsed yet, to there might not be a backlink. This accessor handles both cases correctly and avoids crashes.
