    ir_to_mesa: Generate gl_program_parameter list by walking the GLSL IR.

    Generate the program parameters list by walking the IR instead of by
    walking the list of linked uniforms.  This simplifies the code quite a
    bit, and is probably a bit more correct.  The list of linked uniforms
    should really only be used by the GL API to interact with the
    application.
