In general, I think I like this. The CPP was fine and I in general prefer
it when practical but this is probably justified in light of the constant
folding stuff. Good work on making of look very similar to the old
nir_opcodes.h. Only 1 comment below.

Now, we

Your concatenation of these strings below seems odd. I suppose the spaces
make it OK, but I'm not sure I like it. We can change that easily enough
later so I won't block on that.

This is a functional change. When I pushed the code to add algebraic
properties, I left these non commutative as I think that discussion is
still ongoing. Since none of this is turned on yet, it probably doesn't
matter whether we mark it or not. That said, it should be a separate
patch and not hidden behind deleting and recreating a file.
