Kaining Zhong aab0f2264a [lld-macho] Fix dangling string reference when adding frameworks
In Driver.cpp, addFramework used std::string instance to represent the path of a framework, which will be freed after the function returns. However, this string is stored in loadedArchive, which will be used later to compare with path of newly added frameworks. This caused https://bugs.llvm.org/show_bug.cgi?id=52133. A test is included in this commit to reproduce this bug.

Now resolveDylibPath returns a StringRef instance, and it uses StringSaver to save its data, then returns it to functions on the top. This ensures the resolved framework path is still valid after LC_LINKER_OPTION is parsed.
