Ah, yes, that's tricky. We have something sort of similar in (e.g.) `SymbolFileDWARF::GetDIEToType()` which returns the DWARFDebugMap die-to-type map when dealing with a MachO .o files. It's not completely ideal, but I think it wouldn't be *too* bad if we had a SymbolFileDWARF function to return the ID of the "main" module.

Alternatively, since main symbol file which creates the type system (and the type system creates the DWARFASTParser), we may be able to plumb the module ID to the DWARFASTParser constructor.
