Previously dllimport variables inside of template arguments relied on not using the C++11 codepath when -fms-compatibility was set. While this allowed us to achieve compatibility with MSVC, it did so at the expense of MingW. Instead, try to use the DeclRefExpr we dig out of the template argument. If it has the dllimport attribute, accept it and skip the C++11 null-pointer check. llvm-svn: 211766
