This patch is the wrong approach to fixing this bug -- the
updating of the IFSR needs to be done when the exception
is taken, not when we translate the breakpoint instruction.

I'll put this on my todo list. If you happen to have a convenient
test case demonstrating the problem, that would make a fix happen
faster ;-)
