We basically duplicate the height map branch plugged into the bump node, and tag each node in each branch as dx/dy/ref using `branch_tag`. Then we add a one pixel offset on the texture coordinates if the node is tagged as dx or dy. The dx/dy branches are plugged into (new) hidden sockets on the bump node. This match cycles bump better but have a performance impact. Also, complex nodetrees can now become instruction limited and not compile anymore.
