偶有闲暇，添加了对结构的支持。也增加了对typedef structname synonym的支持。
技巧：
- 结构成员在解析时转换成相对结构于的起始地址之偏移。
- 在运行时计算成员的实际地址（运行时变量才会分配地址 ）。
- 成员按ValueOfPointerIndiction方式访问。
示例代码：
struct StructA { int a; int b; }; StructA theA; theA.a = 1; theA.b = 2; print("theA.a=%i\ntheA.b=%i", theA.a, theA.b); StructA *ptheA = &theA; ptheA->a = 3; ptheA->b = 4; print("theA.a=%i\ntheA.b=%i", theA.a, theA.b); print("ptheA->a=%i\nptheA->b=%i", ptheA->a, ptheA->b);结果输出：
