I'm a little bothered by that question. It's at least the second time
it's been asked of me.

Until both of our backends are accepting NIR by default I don't think
that's it's reasonable to stop adding optimizations to GLSL IR,
especially when they're as simple as this.

Beyond that, as a free software developer I appreciate when someone
does something that indirectly benefits me. If I have the opportunity
to do likewise, I try to.
