David Blaikie 6343f5cfef DebugInfo: partially revert cleanup committed in r209680
I'm not sure exactly where/how we end up with an abstract DbgVariable
with a null DIE, but we do... looking into it & will add a test and/or
fix when I figure it out.

Currently shows up in selfhost or compiler-rt builds.
