Sounds good, I added some more comments in the test about the debug names. From
looking into the code, it seems like having the debug names table allows for
the lazy loading w/ `DebugNamesDWARFIndex ` since we avoid calling the `Index`
[method](https://github.com/llvm/llvm-project/blob/2ab9c35ea93f8557827d4cadcceb05e4eed2d30a/lldb/source/Plugins/SymbolFile/DWARF/ManualDWARFIndex.cpp#L34)
in `ManualDWARFIndex`, and only trigger loading if `GetNonSkeletonUnit` gets
[called](https://github.com/llvm/llvm-project/blob/2ab9c35ea93f8557827d4cadcceb05e4eed2d30a/lldb/source/Plugins/SymbolFile/DWARF/DebugNamesDWARFIndex.cpp#L121).
