This lets us support indirect access to UBOs easily. The existing constant special case disappears too, since the peephole optimizer can inline the constant later. (note: this is too conservative since we can go up to 16-bit immediates...) Unfortunately, nir_opt_algebraic can't seem to optimize expressions like "((a << 3) + 4) >> 2" to "(a << 1) + 1" which would be necessary for reasonable perf out of this...
