* tic80-opc.c (tic80_predefined_symbols): Table of name/value
pairs for all predefined symbols recognized by the assembler. Also used by the disassembling routines. (tic80_symbol_to_value): New function. (tic80_value_to_symbol): New function. * tic80-dis.c (print_operand_control_register, print_operand_condition_code, print_operand_bitnum): Remove private tables and use tic80_value_to_symbol function.
