[Bf-cycles] test Openclcc to compile the blender cycles kernels

Hi,
Thanks for your consideration.

So after doing the first step...the remaining issue would be "optimizing
further for the graphics card"...
the question from here would be,
what kinda optimizations?
what will happen if the developers remove these optimizations?(make it
generic OR  i.e. splitting the optimization side of the kernel up from the
first step::::::::::::making it an option in blenders preferences )
What if this is tried and tested ?
Or (alternatively)...
Chunk the kernel into smaller parts i.e. main(all the shaders/texture
stuff)...nodes(when people start working on nodes, this part of the kernel
is compiled)...etc (if i remember correctly you did say that you wanted
cycles to be modular)

Kind Regards
Nazim Mer
