9ba134b463 Add several unlikely() macros
Based off of perf-based prediction misses these seem to be the
lowest-hanging fruit for quick (albeit small) improvements. These are
based on:

* baking a complex lightmap
* running platformer 3d
* running goltorus

a402efeb72 Tweak OpenMP parameters for lightbaker
On higher threadcount systems this allows for better utilization. On my
16 thread box CPU use goes from 10 - 11 threads to a steady 15 threads
on the Sponza scene.

Baking time goes from ~10:00 to ~07:30 for me. On lower threadcount
systems I expect some improvement also but likely a little less.

be4448bd1f Use a more naive RNG for the lightmapper
This speeds up the lightmapper by about 10% with no visible impact. A
comparison is up here:
