libstdc++/3150: revert 2001-11-30 commit.

2002-01-09  Paolo Carlini <pcarlini@unitus.it>

	libstdc++/3150: revert 2001-11-30 commit. DR266 only means
	that the destructors should be removed from the descriptions
	in the standard: writing them explicitly allows the vtable
	heuristic to work. For additional information see:
	http://gcc.gnu.org/ml/libstdc++/2002-01/msg00090.html
	http://gcc.gnu.org/ml/libstdc++/2002-01/msg00110.html
	http://gcc.gnu.org/ml/libstdc++/2002-01/msg00155.html
	* libsupc++/exception (bad_exception::~bad_exception()):
	Reintroduce declaration.
	* libsupc++/new (bad_alloc::~bad_alloc()): Same.
	* libsupc++/typeinfo (bad_cast::~bad_cast()): Same.
	(bad_typeid::~bad_typeid()): Same.
	* libsupc++/eh_exception.cc (bad_exception::~bad_exception()):
	Reintroduce definition.
	* libsupc++/new_handler.cc (bad_alloc::~bad_alloc()): Same.
	* libsupc++/tinfo.cc (bad_cast::~bad_cast()): Same.
	(bad_typeid::~bad_typeid()): Same.
