[PATCH] Remove non-standard std::copy_exception function

[Jonathan Wakely]

We should have removed this function years ago. It was the original
name for std:make_exception_ptr in C++0x drafts, which we kept 
for backwards compatibility, but deprecated since 4.9.0.

It's not in any C++ standard, so should be removed now.

        * libsupc++/exception_ptr.h (copy_exception): Remove deprecated
        non-standard function.

Tested powerpc64le-linux, committed to trunk.
