Add 20222-data-bank to regression test suite. This exercises handling of 16-bit operands with inter- and intra-bank references, and tests the smartness in "smart PLB". Also, update a couple of older tests that broke because the DBR is no longer always the same as the PBR. This just required adding "B=K" in a few places to restore the original output.
