[PATCH] D56678: [DebugInfo][DAG] Allow creation of DBG_VALUEs in blocks where the operand is not used

Interesting. If I remember correctly this is similar to something I played around with half a year ago (as a preparation before prohibiting CodeGenPrepare::placeDbgValues to move DBG_VALUE between basic blocks (or even to disable CodeGenPrepare::placeDbgValues completely)). I'll have a closer look at this when I'm at the office.  I'll also try to remember if I had some specific reasons for not moving forward with my attempt at doing this - it has been bothering me that I never found the time to finalize that patch.
