When parsing something that looks like an ill-formed protocol-qualifier list without a leading type (e.g., <#blah#>), don't complain about it being an archaic protocol-qualifier list unless it actually parses as one. llvm-svn: 119805

// RUN: %clang_cc1 -fsyntax-only -verify %s
// FIXME: We could do much better with this, if we recognized
// placeholders somehow. However, we're content with not generating
// bogus 'archaic' warnings with bad location info.
C++ support for Objective-C lightweight generics. 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.
