[Fix]: ir_print_const() prints enclosing quote or not

Current ir_print_const() will by default print out the enclosing double
quote for any string, but this will lead to syntax error in dumped dot
file by ir_dump_dot() reported by 'dot' command.

ir_print_const() now has the fourth parameter to indicate whether prints
out the enclosing double quote(") or not.

OLD: ir_print_const(const ir_ctx *ctx, const ir_insn *insn, FILE *f)
NEW: ir_print_const(const ir_ctx *ctx, const ir_insn *insn, FILE *f, bool quoted)
