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.
