  -----------
  [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.
