8d6e5e2fee Cycles: update build configurations to include CUDA sm_35 architecture. When using
a compiler older than CUDA 5.0 it will give a warning and skip this architecture.

16204bd647 Cycles: prepare to make CUDA 5.0 the official version we use
* Add CUDA compiler version detection to cmake/scons/runtime
* Remove noinline in kernel_shader.h and reenable --use_fast_math if CUDA 5.x
  is used, these were workarounds for CUDA 4.2 bugs
* Change max number of registers to 32 for sm 2.x (based on performance tests
  from Martijn Berger and confirmed here), and also for NVidia OpenCL.

Overall it seems that with these changes and the latest CUDA 5.0 download, that
performance is as good as or better than the 2.67b release with the scenes and
graphics cards I tested.

ab2c273b12 Added GPL header to sconscripts!
Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...

* Added missing bitness info to the nvcc_flags. 
This makes sure that the nvcc compiler builds the correct cubins.

b7649ea757 Cycles / CUDA Kernel compile:
* Added option "WITH_BF_CYCLES_CUDA_THREADED_COMPILE" for the people who have much RAM (8 or more) and can compile several kernels at the same time. If enabled, it uses the general BF_NUMJOBS flag.
* The option is off per default.

cd1e78f1b7 Cycles: scons cuda kernel compile now does one kernel at a time, to reduce memory
usage.

45de380771 Cycles
* Compile all of cycles with -ffast-math again
* Add scons compilation of cuda binaries, tested on mac/linux.
* Add UI option for supported/experimental features, to make it
  more clear what is supported, opencl/subdivision is experimental.
* Remove cycles xml exporter, was just for testing.
