nir: Store num_direct_uniforms in the nir_shader.
Storing this here is pretty sketchy - I don't know if any driver other than i965 will want to use it. But this will make it a lot easier to generate NIR code at link time. We'll probably rework it anyway. (Ian suggested making nir_assign_var_locations_scalar_direct_first simply modify the nir_shader's fields, rather than passing pointers to them. If this stays long term, we should do that. But Jason and I suspect we'll be reworking this area again in the near future.)
