Gathers information for time spent in the various managers or object (Film, Camera, etc.) being updated in Scene::device_update. The stats include the total time spent in the device_update methods as well as time spent in subroutines (e.g. bvh build, displacement, etc.). This does not qualify as a full blown profiler, but is useful to identify potential bottleneck areas. The stats can be enabled and printed by passing `--cycles-print-stats` on the command line to Cycles, or `-- --cycles-print-stats` to Blender.
