*
* 这是一个IR优化Pass用于将LoadInst和StoreInst中包含的多维数组索引
* 显式地转换为IR中的BinaryInst乘法和加法序列并生成带有线性偏移量的
* LoadInst/StoreInst。
*
* 目的确保在寄存器分配之前所有中间地址计算的结果都有明确的IR指令和对应的虚拟寄存器
* 从而避免在后端DAG构建时临时创建值而导致寄存器分配缺失的问题。
*
* SysY语言特性
* - 无指针类型所有数组访问的基地址是alloca或global的AllocaType/ArrayType
* - 数据类型只有int和float且都占用4字节。
* - LoadInst和StoreInst直接接受多个索引作为额外操作数。
