    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).
