<pre>According to your data, there were couple of cases where performance improved
up to 10-30% (smoking guns, urban terror, TF2, zbuffer), with the attached test
patch.
However, (as expected), it reduced performance in many more tests and the
difference was *much* larger, up to >70% percent (in GLB fill test and sampler
bound pixel shader test).
Based on your data, this bug should be closed as WONTFIX.
(ZBuffer being better with single span is a bit worrying, as its performance
isn't currently quite what it should be.)</pre>
