This may or may not still be relevant (haven't figured out all the things I
need to try out master branch), but I got as far as finding an out-of-bounds
write in brw_nir_setup_glsl_uniform().  I added:

  assert(uniform_index < stage_prog_data->nr_params);

Just before:

  stage_prog_data->param[uniform_index++] = BRW_PARAM_UNIFORM(idx);

And this assert does fire.  But I think I'll try building master before going
any further with debugging this.
