feat(ast2ir): 实现C11类型提升系统并重构HIR基本块管理
- 新增 scc_ast2ir_promote.c 实现整数提升(6.3.1.1)和寻常算术转换(6.3.1.8) - 重构 HIR Builder: bblock → create_bblock + append_bblock,引入BBList链表管理 - AST2IR 全面集成类型提升:二元运算、赋值、函数调用参数、自增/自减操作符 - 变参函数支持:跳过 ... 假参数,实现默认参数提升(float→double等) - 简化 HIR Dump 实现 - MIR: Win64 ABI改进、x86指令选择优化 - 新增 printf 测试用例
