Cycles: Support multithreaded compilation of kernels This patch implements a workaround to get the multithreaded compilation from D2231 working. So far, it only works for Blender, not for Cycles Standalone. Also, I have only tested the Linux codepath in the helper function. Depends on D2231.

In cycles debug mode (256) you can set unmark the opencl single program file, what reduces the compilation time even further (bmw 17 seconds, barbershop 53 seconds).
