Thomas Dinges e796581655 Cycles: Refactor of constant fold. ...

* Move constant folding from nodes to the shader graph. This way it's part of our (later) 4-step optimization process.
* Instead of only doing a one level constant fold, we can now do a recursive constant fold, allowing us to simplify shaders much further.
Constant folding is implemented for Blackbody, Math and VectorMath nodes.

Example (the highlighted nodes are removed before rendering):
