* Pass socket links and values in structs for each SVM node. * Always pass default values along with stack offset, encoded in SVMInputFloat and SVMInputFloat3. For slightly more efficient memory access the stack offset is encoded in a NaN float. * Simplify SVMCompiler API to use input_float, input_float3 input_link and output functions, instead of manual stack assignment. This was a leftover from early CUDA versions and old GPUs, where data was stored in textures as there was no L1/L2 cache for global memory.
