Added a new preprocessor macro: __has_declspec_attribute. This can be used as a way to determine whether Clang supports a __declspec spelling for a given attribute, similar to __has_attribute and __has_cpp_attribute. llvm-svn: 223467

Introduce the _Clang scoped attribute token. Currently, we only accept clang as the scoped attribute identifier for double square bracket attributes provided by Clang, but this has the potential to conflict with user-defined macros. To help alleviate these concerns, this introduces the _Clang scoped attribute identifier as an alias for clang. It also introduces a warning with a fixit on the off chance someone attempts to use __clang__ as the scoped attribute (which is a predefined compiler identification macro). llvm-svn: 346521

Support accepting __gnu__ as a scoped attribute namespace that aliases to gnu. This is useful in libstdc++ to avoid clashes with identifiers in the user's namespace. llvm-svn: 345132
