Severity: 3Secondary functionality broken

To reproduce:

1. Download attached project "DrawInstanceIndirect.zip" and open in Unity
2. Open "1" scene

4. Open Profiler window

Expected results: In Rendering part, there will be all Instancing info collected
Actual results: In Rendering part, there will be no Instancing info collected

Notes:
- This issue appears both on Windows and OSX
- It seems that Draw call, triangles, and vertices info can't be collected when using Graphics.DrawMeshInstancedIndirect to draw objects

Reproduced on Unity 2017.1.4p1, 2017.2.3p1, 2017.3.2f1, 20174.5f1, 2018.1.5f1, 2018.2.0b8 and 2018.3.0a1

Resolution Note:

We didn't count any stats for "indirect" draw because indirect means the data (number of primitives & instances count) is generally generated by the GPU. So we don't want to stall the GPU to read back data from GPU to CPU.
