Restore pc on watchpoint hits (Jan Kiszka)
In order to provide accurate information about the triggering instruction, this patch adds the required bits to restore the pc if the access happened inside a TB. With the BP_STOP_BEFORE_ACCESS flag, the watchpoint user can control if the debug trap should be issued on or after the accessing instruction.
