[PATCH] D41701: [DAG] Teach BaseIndexOffset to correctly handle with indexed operations

[Eli Friedman via Phabricator via llvm-commits]

================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:13360
       int64_t LdOffset = 0;
       if (LdBasePtr.getBase().getNode()) {
         // The base ptr must be the same.
----------------
Does this null check still work properly given that BaseIndexOffset::match can return a null base?
