[PATCH, PR56193] - Wrong test operator for basic_ios in C++11

[Ed Smith-Rowland <3dw4rd at verizon dot net>]

greetings,

On SO someone noticed that g++ still has in the basic_ios class
  operator void*();
instead of
  explicit operator bool() const;
The old C++98 operator allows things like
  std::cout << std::cout;

This patch changes the stream test operator for C++11 and onwards.

This patch builds and tests clean on x86_64-unknown-linux.
