T61463: Separate Baking kernels Cycles OpenCL: Split baking kernels in own program Fix T61463. Before this patch baking was part of the base kernels. There are 3 baking kernels that and all 3 uses shader evaluation. Only for one of these kernels the functionality was wrapped in the __NO_BAKING__ compile directive. When you start baking this leads to long compile times. By separating in individual programs will reduce the compile times. Also wrapped all baking kernels with __NO_BAKING__ to reduce the compilation times.
