Fix instruction length calculation for TFM compatibility operations The compatibility operations for TFM (TFRP, COPY+, etc.) were using the opcode as the length instead of the length of the opcode as the length. This corrects that oversight. Interestingly, this error has been present forever which gives a fair indication that almost nobody uses these compatibility instructions.
