This is to highlight places where we (probably unintentionally) construct an `Address` object from an already resolved address, making it unresolved again. See the changes in `DynamicLoaderDarwin.cpp` for a quick example. Also, use this constructor instead of `Address(lldb::addr_t file_addr, const SectionList *section_list)` when `section_list` is `nullptr`.
