CSKYDisassembler tries to disassemble register MC operand from register num for different register class, and also handles immediate num and carry flag operand which is not encoded in instruction binary. Also enhance the printer of instruction to accept sub-option to control the print format. Sometimes, it prefers to print number in hex, especially when immediate number represents symbol address.
