[PATCH] D44610: [SelectionDAG] Support multiple dangling debug info for one value

[Adrian Prantl via Phabricator via llvm-commits]

To see any difference you probably need to compile a heavily templated C++ program with lots of inlining. That said, I don't think that this patch will have a huge performance impact even there, since we don't propagate dbg.values beyond basic blocks outside of their lexical scopes.
