      Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating · fb19f940
      Dan Gohman authored
      the need for a flavor operand, and add a new SDNode subclass,
      LabelSDNode, for use with them to eliminate the need for a label id
      operand.
      
      Change instruction selection to let these label nodes through
      unmodified instead of creating copies of them. Teach the MachineInstr
      emitter how to emit a MachineInstr directly from an ISD label node.
      
      This avoids the need for allocating SDNodes for the label id and
      flavor value, as well as SDNodes for each of the post-isel label,
      label id, and label flavor.
