Mai Lavelle	087331c495	Cycles: Replace __MAX_CLOSURE__ build option with runtime integrator variable ... Goal is to reduce OpenCL kernel recompilations. Currently viewport renders are still set to use 64 closures as this seems to be faster and we don't want to cause a performance regression there. Needs to be investigated.

Hristo Gueorguiev	6bf4115c13	Cycles: Split kernel - sort shaders ... Reduce thread divergence in kernel_shader_eval. Rays are sorted in blocks of 2048 according to shader->id. On R9 290 Classroom is ~30% faster, and Pabellon Barcelone is ~8% faster. No sorting for CUDA split kernel.
