I didn't know of a different way of doing it - seeing that the existing 
code prior to this just did a manual X86::JMP32m with a memory operand, I 
tried to extend it in a way making it work for these other formats as 
well (and the issue wasn't raised in review either).

How would I invoke the proper jump table lowering instead?
