Cycles: change svm node decoding for more efficient code generation on GPU
...
These functions no longer accept NULL. They were renamed for clarity and to
avoid hidden merge issues.

CUDA is working correct without it now, and it's more efficient not to do this.

Note this is not supported, there exists no geometry at this point, but
it should not crash at least.

Cycles: add bevel shader, for raytrace based rounded edges.
...
The algorithm averages normals from nearby surfaces. It uses the same
sampling strategy as BSSRDFs, casting rays along the normal and two
orthogonal axes, and combining the samples with MIS.
The main concern here is that we are introducing raytracing inside
shader evaluation, which could be quite bad for GPU performance and
stack memory usage. In practice it doesn't seem so bad though.
Note that using this feature can easily slow down renders 20%, and
that if you care about performance then it's better to use a bevel
modifier. Mainly this is useful for baking, and for cases where the
mesh topology makes it difficult for the bevel modifier to work well.
