[Bf-committers] Builders: please upgrade to CUDA 5.0

Hi all,

I'd like to switch from CUDA 4.2 to 5.0 for official builds and
buildbots, and I suggest everyone making own builds to switch too.
https://developer.nvidia.com/cuda-downloads

Reasons:
* Support NVidia Titan graphics cards (sm_35)
* Significant Cycles speedups for some scenes and graphics cards
* Builds with visual studio 2012
* Means we can remove some workarounds for CUDA 4.2 bugs

I've updated the configurations to include sm_35, but it will not give
a build error yet if this can't be compiled, just a warning.

If you get an error installing it regarding incompatible GCC versions,
you can run the installer with the -override flag and remove this line
from /usr/local/cuda-5.0/include/host_config.h after installation.
Since we do no directly link the CUDA code into our C/C++ code this is
not a real compatibility issue for us.
#error -- unsupported GNU version! gcc 4.7 and up are not supported!

Thanks!
