Brecht Van Lommel 741f17f05b Cycles CUDA: make CUDA toolkit 6.0 the official supported version.
This also updates the configurations to build kernels for compute capability
5.0 cards, when using and older CUDA toolkit version this will be skipped.

Also includes tweaks to improve performance with this version:
* Increase max registers on sm_30, sm_35 and sm_50
* No longer use texture storage on sm_30
