Implement setcc instructions#184

[kevinramharak]

! Needs feedback and additional changes before being merged !

This is a PR to get some feedback on the changes in architecture before implementing the whole family of instructions + tests.

The changes are kept to a minimal:

• Some classes and its methods are set to public from private or package private. This is mandatory for instructions to implement their own encoding and execute logic.
• A big change would be that aliased instructions have to extends their aliased instruction (Blocks #190.). The aliased instruction needs an additional constructor signature to set the correct mnemonic.

Because the @Override encode(...) function has no other method of knowing its mnemonic than getMnemonic the SETcc family needs its aliases to extends the base SetccInstruction. This will provide the correct return value to getMnemonic when the assembler calls encode on an instruction. This will have no impact on the CPU executing the instruction since the CPU always looks up an instruction based on its opcode.

The SetccInstruction does a bit to much for my liking but spreading the logic to each sub class will (IMO) not improve the readability. I am also not sure if this is possible with the current Assembler and CPU implementations.

Ok, I added all tests. Found a few bugs while writing them. The PR is getting huge but im not done yet. I will still have to make changes to the front end editor. Ill try to get that done in the weekend. Once thats finished this PR should be ready to go.

@simon987 I added the syntax highlighting and editor support. The front end is a bit of a mess, but thats another issue.

This is a lot of commits and files tough a lot is boiler plate. If this PR gets merged ill update the wiki where applicable

thank you

wups i think i forgot to add the aliases to the default instruction set. I can fix this at thr end of today
