The __kindof type qualifier can be applied to Objective-C object (pointer) types to indicate id-like behavior, which includes implicit "downcasting" of __kindof types to subclasses and id-like message-send behavior. __kindof types provide better type bounds for substitutions into unspecified generic types, which preserves more type information. llvm-svn: 241548
