As same as other results, introduce exit_pass and exit_fail
functions so that we can easily understand what will happen.

- Restore "this must fail" comment (Thanks Steve!)

Sorry, I should have caught this before. But can you use $PASS and
$FAIL in the functions? In case we want to override them in the future?
exit_pass() {
exit $PASS
}
exit_fail() {
exit $FAIL
}

No, as I've said, those are ftracetest internal vars :(
And also you can not override it because each testcase script can
exit with error code of executed command in failure case. IOW,
the error code propagates caller's exit code. So we can not
controll it. This means you can just expect the exit code
0 or !0.
Thank you,
