Data Bank Register management, part 6 (of 6)

Browse Source 
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.
