Add subtest test_sync_merge that tests merging fences and the validity of the
resulting merged fence.

Can I suggest the pattern:

fence_merge = -1;
for (i = 0; i < ARRAY_SIZE(in_fence); i++) {
	in_fence[i] = sw_sync_fence_create(timeline, i + 1);
	fence_merge = sync_merge(fence_merge, in_fence[i]);

	active = sync_fence_count_status(in_fence[i],
					 SW_SYNC_FENCE_STATUS_ACTIVE);
	igt_assert_f(active == 1, "in_fence[%d] has too many active fences\n", i);

	igt_assert(!sync_fence_count_status(in_fence[i],
					    SW_SYNC_FENCE_STATUS_SIGNALED));
	igt_assert(!sync_fence_count_status(fence_merge,
					    SW_SYNC_FENCE_STATUS_SIGNALED));
}

> +	/* confirm that fence_merge is not signaled until the max of fence 0,1,2 */
for (i = 0; i < ARRAY_SIZE(in_fence); i++) {
	sw_sync_timeline_inc(timeline, 1);

	signaled = sync_fence_count_status(in_fence[i],
					   SW_SYNC_FENCE_STATUS_SIGNALED);
	igt_assert_f(signaled == 1, "in_fence[%d] did not signal\n", i);

	signaled = sync_fence_count_status(fence_merge,
					   SW_SYNC_FENCE_STATUS_SIGNALED);
	active = sync_fence_count_status(fence_merge,
					 SW_SYNC_FENCE_STATUS_ACTIVE);
	if (i + 1 == ARRAY_SIZE(in_fence)) { /* all signaled -> merge complete */
		igt_assert_f(active == 0 && signaled == 1,
			     "fence_merge did not signal\n");
	} else {
		igt_assert_f(active == 1 && signaled == 0,
			     "fence_merge signaled too early\n");
	}

	close(in_fence[1]);
}
