The TRIS and OPTION instructions have never been in the datasheets for the
newer 14bit devices such as the 16F87x, even though they do (did?) support
them.  Microchip have been recommending not to use these very usefull
instructions for years.  It's possible the later dir shrunk devices have had
support for these instructions removed.

Use the older 16bit MPLAB (5.7.4 is the latest) which should be capable of
dissasembling these opcodes.
