Does this help fix the CTS test or are you just adding it because you
noticed it?

Also I'd probably just add this to the ES check bellow.

   /* GLSL 1.10 and ESSL do not allow implicit conversions.
    * If there is no state, we're doing intra-stage function
    * linking where these checks have already been done.
    */
   if (state && (state->es_shader || !state->is_version(120, 0)))
      return false;
