Add the new AppContainer characteristic which is import for Windows Store (Metro) compatible applications. Add the new Control Flow Guard flag to bring the enumeration up to date with the current values as of Windows 8.1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211855 91177308-0d34-0410-b5e6-96231b3b80d8
