Parsing, semantic analysis, and AST for Objective-C type parameters. Produce type parameter declarations for Objective-C type parameters, and attach lists of type parameters to Objective-C classes, categories, forward declarations, and extensions as appropriate. Perform semantic analysis of type bounds for type parameters, both in isolation and across classes/categories/extensions to ensure consistency. Also handle (de-)serialization of Objective-C type parameter lists, along with sundry other things one must do to add a new declaration to Clang. Note that Objective-C type parameters are typedef name declarations, like typedefs and C++11 type aliases, in support of type erasure. Part of rdar://problem/6294649. llvm-svn: 241541

Implement variance for Objective-C type parameters. Introduce co- and contra-variance for Objective-C type parameters, which allows us to express that (for example) an NSArray is covariant in its type parameter. This means that NSArray<NSMutableString *> * is a subtype of NSArray<NSString *> *, which is expected of the immutable Foundation collections. Type parameters can be annotated with __covariant or __contravariant to make them co- or contra-variant, respectively. This feature can be detected by __has_feature(objc_generics_variance). Implements rdar://problem/20217490. llvm-svn: 241549
