Those that don't fall into the following sets:
- the real illegal opcode
- {EmulOp,A,F}-line traps
- whose handler is not op_illg_1

As a reseult, there are around 9500 opcodes remaining.

In fact, I will now cut that set into two sets:
- one for compiled code that can be flushed
- one for compiled code from ROM

Then, it's not impossible that we get a big portion of ROM compiled
afterwards... Unfortunately, ROM A-Traps are probably not the most
useful (except parts of QuickDraw), are they ?

If I remember well, ROM is patched only once whereas rsrc patches could
be rerun at anytime. So that approach could work.

Bye.
