I was wondering about the first comment. Some methods like `MachOObjectFile::isSectionVirtual` in libObject are what we need but ObjectYAML employs its own data structure `MachOYAML::Object`.

Adding some macros or inline functions into `include/llvm/BinaryFormat/MachO.h` and refactoring libObject as well as here using them would be better way I suppose. This should be separate patch by the way.
