Pull in r158245 from upstream clang:

  [C++11 Compat] Fix breaking change in C++11 pair copyctor.

  While this code is valid C++98, it is not valid C++11. The problem
  can be reduced to:

  class MDNode;

  class DIType {
    operator MDNode*() const {return 0;}
  };

  class WeakVH {
    WeakVH(MDNode*) {}
  };

  int main() {
    DIType di;
    std::pair<void*, WeakVH> p(std::make_pair((void*)0, di)));
  }

  This was not detected by any of the bots we have because they either
  compile C++98 with libstdc++ (which allows it), or C++11 with libc++
  (which incorrectly allows it). I ran into the problem when compiling
  with VS 2012 RC.

  Thanks to Richard for explaining the issue.

This fixes building clang 3.1 on stable/9 with libc++ in C++11 mode.

This is a direct commit to stable/9, since there is no separate commit
in head which has just this particular change, and I do not want to do a
full import at this time.
