[PATCH] D22858: Fix DbgValue handling in SelectionDAG.

[Nirav Davé via llvm-commits]

The fact that Hans still found the error after the r277027 patch is
evidence that the second part of this patch is necessary as well (testing
with Ismall showed that r277027 was necessary so both are needed). I think
that indirectly answers the remaining question of whether copying or moving
debug values is the right thing to do and we should be okay upstreaming
this patch.
