Move ObjCPropertyDecl to before ObjCContainerDecl.
After we add ObjCPropertyDecl::isClassProperty, we can use it in ObjCContainerDecl to define filter to iterate over instance properties and class properties. This is the first patch in a series of patches to support class properties in addition to instance properties in objective-c. rdar://23891898 llvm-svn: 258727
