  /* No extra fields, but adds the invariant:

     (INSN_P (X)

      || JUMP_TABLE_DATA_P (X)
      || BARRIER_P (X)
      || LABEL_P (X))

     i.e. that we must be able to use the following:
      INSN_UID ()
      NEXT_INSN ()
      PREV_INSN ()
    i.e. we have an rtx that has an INSN_UID field and can be part of
    a linked list of insns.

  /* Returns true if this insn has been deleted.  */

  bool deleted () const { return volatil; }

  /* Mark this insn as deleted.  */

  void set_deleted () { volatil = true; }

  /* Mark this insn as not deleted.  */

  void set_undeleted () { volatil = false; }
