For this WIP, I added more TLCS900H instructions. All of the
ADC,ADD,SBB/SBC,SUB,AND,OR,XOR.CP,PUSH,POP instructions are in.

Still an incredible amount of work left to do on this core ... it has all kinds
of novel instructions that aren't on any other processors.

Still no disassembler support yet, so I can't even test what I'm doing. Fun!
