Yeah, and it also won't make sense to do it until we can get the NIR
optimizations up to par with the GLSL ones so that we can disable all
the GLSL ones after linking and not get a regression. This would
involve porting all the GLSL optimizations to NIR, which now that I
think about it actually seems like a quite doable GSoC project -- it's
a pretty well-defined task and there are lots of little optimizations
to translate so it's easy to make progress, although porting all of
them over might be too much for one summer.
