I felt free to the following, tested with dejagnu-1.4.4.
There's no separate kpass support (and no need for any, for the
same reason you don't need to add separate xpass support. :-)

	* lib/sim-defs.exp (run_sim_test): Support "xfail" and "kfail".
	In head comment, mention that output specifications concatenate.
