nir/inline_uniforms: Add inot condition support

Browse source 
From the 96c19d23c9 commit message:

    Ever since 4246c2869c and 7d85dc4f35 loop unrolling can no
    longer depend on inot being eliminated from the loop
    terminator condition so we need to be able to handle it.

Support these conditions here too.
