When multiple DWP files are merged together and duplicate DWO IDs are found it's currently difficult to give an actionable error message - the DW_AT_name of the CU could be provided, but might be identical (if the same source file is built into two different configurations), which doesn't help the user identify the problem. When no intermediate DWP files are generated, the path to the two DWO files could be provided - but is lost once the DWOs are merged into a DWP. So, include the name of the DWO (dwo_name) in the split file so that collissions involving a source CU from a DWP can be better diagnosed. (improvements to llvm-dwp using this to come shortly) llvm-svn: 264316
