Currently, maphash.Comparable forces its argument to escape if it contains a pointer, as we cannot hash stack pointers, which will change when the stack moves. However, for a string, it is actually okay if its data pointer points to the stack, as the hash depends on only the content, not the pointer. Currently there is no way to write this type-dependent escape logic in Go code. So we implement it in the compiler as an intrinsic. The compiler can also recognize not just the string type, but types whose pointers are all string pointers, and make them not escape. Fixes #70560.
