Stephan Bergmann 5fa9ce570d Fix order of SAL_WARN_UNUSED and DLLPUBLIC for clang-cl
...which, somewhat arbitrarily, expects GNU extension __attribute__((...)) to
come before MSVC extension __declspec(...) with

  MaybeParseGNUAttributes(attrs);
  MaybeParseMicrosoftDeclSpecs(attrs);

in Parser::ParseClassSpecifier (lib/Parse/ParseDeclCXX.cpp).
