ir_to_mesa: Don't assertion fail on remaining GLSL 1.30 ops. 

For hardware drivers, we only have ir_to_mesa called for the purposes
of potential swrast fallbacks (basically never on a 1.30 driver),
which we don't really care about.  This will allow 1.30 to be
implemented without rewriting swrast for it.
