    glsl: Optimize clamp(x, 0, 1) as saturate(x)

    v2: - Check that the base type is float (Ian Romanick)
    v3: - Make sure comments reflect that we are doing a commutative operation
        - Add missing condition where the inner constant is 1.0 and outer
constant is 0.0
        - Make indexing of operands easier to read (Matt Turner)
