Teach C++'s tentative parsing to handle specializations of Objective-C class types (e.g., NSArray<NSString *>) as well as Objective-C protocol qualifiers (id<NSCopying>) by extending type-annotation tokens to handle this case. As part of this, remove Objective-C protocol qualifiers from the declaration specifiers, which never really made sense: instead, provide Sema entry points to make them part of the type annotation token. Among other things, this properly diagnoses bogus types such as "<NSCopying> id" which should have been written as "id <NSCopying>". Implements template instantiation support for, e.g., NSArray<T>* in C++. Note that parameterized classes are not templates in the C++ sense, so that cannot (for example) be used as a template argument for a template template parameter.
