+       *     constant containing the local work-group size of the shader.  The
+       *     size of the work group in the X, Y, and Z dimensions is stored in
+       *     the x, y, and z components.  The constants values in
+       *     gl_WorkGroupSize will match those specified in the required
+       *     local_size_x, local_size_y, and local_size_z layout qualifiers
+       *     for the current shader.  This is a constant so that it can be
+       *     used to size arrays of memory that can be shared within the local
+       *     work group.  It is a compile-time error to use gl_WorkGroupSize
+       *     in a shader that does not declare a fixed local group size, or
+       *     before that shader has declared a fixed local group size, using
+       *     local_size_x, local_size_y, and local_size_z.
+       *
+       * To prevent the shader from trying to refer to gl_WorkGroupSize before
+       * the layout declaration, we don't define it here.  Intead we define it
+       * in ast_cs_input_layout::hir().
