>From the included test case:
```
DW_TAG_module
      DW_AT_name	("DebugModule")
      DW_AT_LLVM_config_macros	("-DMODULES=0")
      DW_AT_LLVM_include_path	("/llvm/tools/clang/test/Modules/Inputs")
      DW_AT_LLVM_apinotes	("m.apinotes")
```
Any additional information that can be collected for the `LVScopeModule`?
