新的go编译器 //1、最小分配内存是8字节. //2、const string转到slice是强转，不会重新分配空间;如果是变量string，那么会对slice重新分配空间. // 2.1、如果const string（s没有重新分配空间），那么剩余空间不够（slice强转)，那么s1/s2也会重新分配空间，所以s1,s2重新分配空间 // 2.2、如果变量string，那么s重新分配空间，导致cap的剩余空间足够，导致s1/s2都还是用s的空间，导致s1,s2的内容相同。 // 2.3、变量string，如果正好8字节，正好在赋值满了，s也满了，所以s1//s2也会重新分配空间，所以s1,s2重新分配空间.
