859 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).
