fca5d45d - [SelectionDAG] Make SelectionDAG::dump(true) usable from debugger (#166722)

[SelectionDAG] Make SelectionDAG::dump(true) usable from debugger (#166722) When called from DAGCombiner, there may be a HandleSDNode allocated on the stack. Since the node is not part of a DAG, we don't allocate an entry for it in the operand counting map and should not attempt to decrement its operand count.
