SPECIAL instructions are *special* instructions that do not participate in 
inline-threading.  They are instructions like the special PREPARE_METHOD which 
is a handler used to lazily prepare a method, etc.

This sould become clearer once you have read chapter 2 of my thesis.  Among 
other special instructions are "slow preparation" instructions [e.g. the version 
of GETSTATIC which does class initialization if necessary].
