glsl: add ir_control_flow_visitor
This is just a subclass of ir_visitor with empty implementations of all
the visit methods for non-control flow nodes.
Used to avoid duplicating that in ir_visitor subclasses.
ir_hierarchical_visitor is another way to solve this, but is less natural
for some applications.
