<pre>The performance counter values for VF part of the pipeline (IA_VERTICES_COUNT,
IA_PRIMITIVES_COUNT) are always 0. Gathering of these counters should be
explicitly enabled in VF_STATE.
According to the specs, the same should apply to *_INVOCATION_COUNT counters,
but those come out fine.
As a workaround, INTEL_DEBUG=stats enables the gathering.</pre>
