      glsl-1.10: Verify pre- and post-inc/dec cannot be l-values · 02550817

      These generators create two kinds of tests.  The first verifies that
      pre- and post-increment/decrement operations cannot be assignment
      targets.  These look like:
      
      uniform float u;
      varying vec4 v;
      
      void main()
      {
          float t = u;
      
          ++t = float(v.x);
          gl_FragColor = vec4(t, v.yzw);
      }
      
      The second kind of test verifies that pre- and
      post-increment/decrement operations cannot be used for function 'out'
      parameters.  These look like:
      
      uniform ivec4 u;
      attribute vec4 v;
      
      void f(out ivec4 p)
      {
          p = ivec4(v);
      }
      
      void main()
      {
          ivec4 t = u;
      
          f(t--);
          gl_Position = vec4(t);
      }
      
      Function 'inout' parameters are not explicitly tested.
      
      A test is generated for both vertex and fragment targets for each
      int and float vector or scalar datatype.  Matrix types and GLSL 1.30
      unsigned types are not tested.
