refactor(ast): 统一记录类型结构并移除成员访问操作符
- 移除了枚举类型的独立结构定义,统一使用record结构 - 移除了成员访问操作符SCC_AST_OP_MEMBER_ACCESS和SCC_AST_OP_PTR_MEMBER_ACCESS - 更新了for循环语句中init字段的类型从scc_ast_type_t*到scc_ast_node_t* - 修改了声明初始化函数以支持统一的记录类型处理 fix(ast2ir): 完善二元表达式处理和for循环代码生成 - 重构了赋值操作符的处理逻辑,通过临时表达式实现复合赋值 - 添加了对for循环语句的完整IR代码生成功能 - 修复了if-else语句中错误的基本块跳转问题 - 改进了标识符未找到时的错误提示信息 chore: 清理代码和修复潜在问题 - 移除了未使用的自动标签生成功能 - 统一了IR基本块标签格式化输出 - 修复了机器码生成中的寄存器存储控制流问题 - 改进了词法分析器中十六进制数字的处理逻辑
