[Bf-cycles] CUDA Toolkit 6.5 and Volume on GPU

[David Fenner]

On GTX titan, mike pan test:

2.71 official                  27.62
vainilla cuda 6.5          28.07
volume cuda 6.5          28.25


Notes: Was testing volumes and with a simple world volume and a lamp now
it's actually much faster than cpu (before gpu was crazy slow). Haven't
tested it with more complex scenes.  I noticed though that in gpu volume
gets always sampled as "distance" sampling, no matter the setting. Cpu
however respects the other settings (equiangular, etc). In distance gpu
much faster and its also faster when bounces are introduced, something that
in older builds really killed gpu performance.
