> Reinstate the check for dbg.value that LSR has changed from single location-op to multi location-op. When LSR makes this change, the single location argument is changed to a DIArglist.  This patch now replaces the DIArglist with a single 'undef'. This will prevent the generation of invalid dbg.value that were causing the crash as reported by @Orlando .

If that change makes the patch not-NFC, please could you add a test for this and mention it in the commit message? Lastly, please can you appease the clang-format bot?
