  -----------
  [Clang] Fix crash in Parser::ParseDirectDeclarator by adding check that token is not an annotation token

In Parser::ParseDirectDeclarator(...) in some cases ill-formed code can cause an
annotation token to end up where it was not expected. The fix is to add a
!Tok.isAnnotation() guard before attempting to access identifier info.
