Description
The undocumented SLL (CB 30-37, and the DDCB/FDCB xx 30-37 forms) has no case in gen_instr_il(), so it falls through to the catch-all il.unimplemented().
Low priority — it only appears in code that deliberately uses undocumented opcodes.

Research direction
Start in gen_instr_il(), where the CB 30-37 and DDCB/FDCB xx 30-37 forms currently fall through to il.unimplemented(). Read the surrounding instruction handling and trace these opcode forms; done means SLL/SL1 is lifted instead of reaching the catch-all path.
