FYI, I don't have write privileges, so I assume someone else needs to run arc land if this is ready to be committed and pushed?

Nice catch!  The instructions they would have messed up, like psubsb/vpsubsb, don't have any unit tests, so it wasn't showing up in testing.  I'll check for a ONEBYTE opcodeType here, add the unit tests, and fix the identation problems in the next diff.
