Vulkan spec 18.8. Primitives Generated Queries: When a generated primitive query for a vertex stream is active, the primitives-generated count is incremented every time a primitive emitted to that stream reaches the transform feedback stage, whether or not transform feedback is active. We can see the order of stages in chapter 27 Fixed-Function Vertex Post-Processing, which shows that the transform feedback stage is before rasterization (and therefore culling). Conclusion is that culled primitives should be included in the primitives generated query. This commit makes sure to emit the primitives generated query code before culling and uses the input primitive count passed to the current wave instead of the exec mask after culling.
