ntt: Use scoped barriers
In addition to bringing us one backend closer to the scoped-only future, this
improves the generated code in cases like:
memoryBarrierBuffer();
memoryBarrierShared();
controlBarrier();
With scoped_barriers + nir_opt_combine_barriers, we now emit only one MEMBAR
instruction (and a BARRIER) rather than two MEMBARs.
