The key point is to add a reference from the opcode to the target address. 
What I did with the '$' script. Then as soon as a label is added or renamed 
at the target address, it will be displayed near all the referring opcodes.

I guess that a proper opcode instruction decoding should do the same:
- First, automatically add a reference to the target address, using the same 
method as the '$' script.
- Then properly implement the PCode operation (in InstructionPrototype 
instance?) to materialize the jsr/jmp behaviour for decompilation.

I'm not familiar with that stuff, though.
