Introduce context-sensitive, non-underscored nullability specifiers (nonnull, nullable, null_unspecified) for Objective-C method return types, method parameter types, and properties. Introduce Objective-C-specific semantics, including computation of the nullability of the result of a message send, merging of nullability information from the @interface of a class into its @implementation, etc . This is the Objective-C part of rdar://problem/18868820. llvm-svn: 240154
