Blender Version
Broken: 13f292d10d3b(blender2.8 HEAD)
Worked: 2.79

Short description of error
Object count and polygon count should ignore instance.

Exact steps for others to reproduce the error
instance.blend

Stats show:
Verts: 12 | Faces: 4 | Objects 1/7

While in 2.79 we would have:
Verts: 3 | Faces: 1 | Objects 1/4

Note, in 2.79 if the group/collection was linked, it would not count it towards the mesh count not even once.
I think in 2.80 we could count each Mesh datablock once.

I'm curious about this change, as the poly count in the status bar always seemed to be related to the amount of geometry drawn. For example, even when making duplicated copies of objects in 2.79 with Alt-D the count would increase. And switching layers (and currently collections) will also change the count, so it is at least somehow related to what is on screen. So what is the point of not counting instanced geometry when that seems to mostly create a confusing relationship between the status bar poly count and what is visible on screen? Hopefully a statistic that is so prominently displayed in the UI should be easy to understand?

@PaulMelis 2.79 got it wrong very differently. For instance, if you link in a group with heavy meshes it would not count towards the geometry count.

Now for 2.80, we count the geometry that has an impact in memory. If you have duplicated copies of a mesh they don't take more memory space (in the RAM anyways).
