Faster object tree building (instancing)

Hi all,
I sped up the object tree building, it's 6x or more faster now.
Here are some scattered Lucy models to demonstrate:
I also fixed the triangles count in the UI so it could show the total number of triangles correctly
Num instances: ~3.8 M
Num triangles per instance: ~28M
Total number of triangles: ~106 trillion triangles
Scene build times:
Lucy scatter test
==============
Old (v3.8.26)
----------
Finished building tree. (Time taken: 35.209 s)
Finished initialisation (Time Taken: 68.02 s)
New (v4.0.x)
-------
Object tree build done. (Time Taken: 5.334 s)
Finished initialisation (Time Taken: 25.40 s)

Awesome, faster object tree building + your faster subdiv will kick in nicely for me, thanks a lot for that!

Would be fun to use Lucy as grass in an arch viz shot just to see if the client notices anything.

I'd like to see how far this can be pushed with lets say 32GB of RAM in a system

Yeah, was just saying. Would be cool to hit a quadrillion!

That's already pushing the RAM quite far (on my 32GB system). I'll try and optimise mem usage a bit and get to 1 quadrillion

Did some more optimisations:
Object tree build done. (Time Taken: 4.027 s)
(was 5.3s in the original post above).
Think I need to stop now...
