* DummyBrain is example how you create you own cpu brain to translate from
* cpu to intel assembler, I have not add DummyBrain to the loader it is not
* need it in our example. When you write you own brain, it must be setup in
* misc.c function LoadPFileImage and PEFileStart, PEFileStart maybe does not
* need the brain you have writen so you do not need setup it there then.
*
* input param:
* cpu_buffer : the memory buffer with loaded program we whant translate
* cpu_pos : the positions in the cpu_buffer
* cpu_size : the alloced memory size of the cpu_buffer
* BaseAddress : the virtual memory address we setup to use.
* cpuarch : the sub arch for the brain, example if it exists more one
* cpu with same desgin but few other opcode or extend opcode
* outfp : the output file pointer
*
* mode : if we should run disambler of this binary or
* translate it, Disambler will not calc the
* the row name right so we simple give each
row a name. In translations mode we run a
* analys so we getting better optimzing and
* only row name there we need.
* value for mode are :
* 0 = disambler mode
* 1 = translate mode intel
*
* return value
* 0 : Ok
* 1 : unimplemt
* 2 : Unkonwn Opcode
* 3 : unimplement cpu
* 4 : unknown machine
