* tic80-dis.c (print_insn_tic80): Print TIC80_OPERAND_RELATIVE

Browse Source 
correctly.  Add support for printing TIC80_OPERAND_BITNUM and
	TIC80_OPERAND_CC, and TIC80_OPERAND_CR operands in symbolic
	form.
	* tic80-opc.c (tic80_operands): Add SSOFF, LSOFF, BITNUM,
	CC, SICR, and LICR table entries.
	(tic80_opcodes): Add and test "nop", "br", "bbo", "bbz",
	"bcnd", and "brcr" opcodes.
