Avoid deprecated warnings about std::auto_ptr in library headers

	* include/backward/auto_ptr.h: Ignore deprecated warnings from use
	of auto_ptr.
	* include/bits/shared_ptr.h: Likewise.
	* include/bits/shared_ptr_base.h: Likewise.
	* include/bits/unique_ptr.h: Likewise.
	* libstdc++-v3/testsuite/20_util/default_delete/48631_neg.cc: Adjust
	dg-error lineno.
	* libstdc++-v3/testsuite/20_util/default_delete/void_neg.cc: Likewise.
	* libstdc++-v3/testsuite/20_util/unique_ptr/assign/48635_neg.cc:
	Likewise.
	* libstdc++-v3/testsuite/20_util/unique_ptr/cons/cv_qual_neg.cc:
	Likewise.
