[dx8] modification to vertex array patch

[Ann and Jason Edmeades]

Please change the following two lines in the previous patch:
+            FIXME("Using fast vertex array code\n");
+            FIXME("Using slow per-vertex code\n");

into
+            TRACE("Using fast vertex array code\n");
+            TRACE("Using slow per-vertex code\n");

I changed the lines to ensure we were driving both cases, and took the diff
without swapping it back - Sorry.
