Overhaul emit logic to use visitor abstraction

- This is in preparation for splitting out HLSL vs. GLSL emit as different cases.

- Along the way, I added more cases to the visitor implementation, to handle visitors with arguments
  - This is getting a bit busy, though, and we might be reaching the breaking point where a more general bit of meta-magic is needed to clean things up (either going further down the ugly template route, or plugging in a more real code generation strategy)
