With the pass order shuffling, code like `(x & 0xf) + (x & 0xfffffff0)` gets optimized to bitfield_select(0xF, x, x). But it would be much better to optimize simply to x. nir_opt_algebraic would do that for us but we run this pass too late for algebraic to save us from ourselves, so be smarter. Observed on dEQP-GLES31.functional.compute.basic.image_atomic_op_local_size_8 with Jay, this saves an instruction there.
