glsl: allow invariant on fragment shader outputs.

From page 27 (page 33 of the PDF) of the GLSL 1.20 spec:

From page 37 (page 43 of the PDF) of the GLSL 1.30 spec:

    " Initially, by default, all output variables are allowed to be
      variant. To force all output variables to be invariant, use the
      pragma

        #pragma STDGL invariant(all)

      before all declarations in a shader. If this pragma is used after
      the declaration of any variables or functions, then the set of
      outputs that behave as invariant is undefined. It is an error to

i965: keep gl_program shader info in sync after gather info

It's possible that nir_shader was cloned and it no longer contains
a pointer to the shader_info in gl_program. So we need to copy
shader_info back to gl_program if that is the case.
