[PATCH 5/6] nptl: Convert some rwlock tests to use libsupport

We have xpthread_rwlock_wrlock and xpthread_barrier_init, which will
perform the error checking for you.  Similarly for a few more functions.

Perhaps it's time to introduce xclock_gettime?

>    if (e == 0)
> -    {

>    else if (e != EINVAL)
> -    {

You could use

  TEST_COMPARE (pthread_rwlock_timedrdlock (&r, &ts), EINVAL);

instead.

Thanks,
