At the point we were calling this, we hadn't necessarily cleaned up derefs via nir_lower_vars_to_ssa, nor movs/vecs via copy propagation, so it wasn't necessarily easy for this pass to see the actual usage of the destination. Moving this later allows us to detect f2f32(txf(...)) and avoid converting it to a 16-bit txf (why convert with ALU instructions when the sampler could do it for us?).
