  Execute trapped instruction after breakpoint is removed
  
  Closes bug #104
  
  When the instruction replaced by a trap instruction is restored by the
  debugger, this instruction is not executed.
  
  Proposed solution:
  
  - Checked for a debug unstall condition plus a trap condition in
  or1200_du(dbg_stall && |except_stop).
  
  - Then, when this event occur, flush the entire pipeline (in or1200_ctrl) and
  set the pc to npc in or1200_genpc(which is equal to the trapped instruction
  address).
