Thanks for the reference! In `GetSeparateDebugInfo`
[here](https://github.com/llvm/llvm-project/blob/d882670d498a29f4e02f357ef9fe07c43de034c8/lldb/source/Plugins/SymbolFile/DWARF/SymbolFileDWARF.cpp#L4185),
the call to `GetDwoSymbolFile` ends up loading all DWO files (even if they
weren't already loaded). I think it'd work if we set the `load_all_debug_info`
to false in the call and do `GetDwoSymbolFile(false)`, in which case we'd have
to add an extra `load_all_debug_info` argument to `GetSeparateDebugInfo` as
well so that other existing use cases for GetSeparateDebugInfo don't get
effected. I can try that instead of adding the new overload.
