	PR libstdc++/31556
	* include/bits/stl_algobase.h (equal(_InputIterator1, _InputIterator1,
	_InputIterator2, _BinaryPredicate), mismatch(_InputIterator1,
	_InputIterator1, _InputIterator2, _BinaryPredicate)): Convert
	predicate return to bool.
	* include/bits/stl_algo.h (__find_if(_InputIterator, _InputIterator,
	_Predicate, input_iterator_tag), search(_ForwardIterator1,
	_ForwardIterator1, _ForwardIterator2, _ForwardIterator2,
	_BinaryPredicate), __search_n(_ForwardIterator, _ForwardIterator,
	_Integer, const _Tp&, _BinaryPredicate, std::forward_iterator_tag),
	__search_n(_RandomAccessIter, _RandomAccessIter, _Integer, const _Tp&,
	_BinaryPredicate, std::random_access_iterator_tag),
	search_n(_ForwardIterator, _ForwardIterator, _Integer, const _Tp&,
	_BinaryPredicate), remove_copy_if(_InputIterator, _InputIterator,
	_OutputIterator, _Predicate), __unique_copy(_ForwardIterator,
	_ForwardIterator, _OutputIterator, _BinaryPredicate,
	forward_iterator_tag, output_iterator_tag),
	__unique_copy(_InputIterator, _InputIterator, _OutputIterator,
	_BinaryPredicate, input_iterator_tag, output_iterator_tag),
	__unique_copy(_InputIterator, _InputIterator, _OutputIterator,
	_BinaryPredicate, input_iterator_tag, output_iterator_tag),
	__unique_copy(_InputIterator, _InputIterator, _ForwardIterator,
	_BinaryPredicate, input_iterator_tag, forward_iterator_tag),
	unique(_ForwardIterator, _ForwardIterator, _BinaryPredicate),
	__partition(_BidirectionalIterator, _BidirectionalIterator, _Predicate,
	bidirectional_iterator_tag), binary_search(_ForwardIterator,
	_ForwardIterator, const _Tp&, _Compare),
	next_permutation(_BidirectionalIterator, _BidirectionalIterator,
	_Compare), prev_permutation(_BidirectionalIterator,
	_BidirectionalIterator, _Compare)): Likewise.
