When we set cpu->cflags_next_tb it is because we want to carefully control the execution of the next TB. Currently there is a race that causes the second stage of watchpoint handling to get ignored if an IRQ is processed before we finish executing the instruction that triggers the watchpoint. Use the new CF_NOIRQ facility to avoid the race. We also suppress IRQs when handling precise self modifying code to avoid unnecessary bouncing.
