New Revision: 277629

Log:
Apply C++20 changes to various iterator types

This ensures that __normal_iterator<T*, C> satisfies the
contiguous_iterator concept, by defining the iterator_concept member
type.

Also update vector<bool>'s iterators, reverse_iterator,
istreambuf_iterator and ostreambuf_iterator to meet the C++20
requirements.

	PR libstdc++/92272
	* include/bits/stl_bvector.h (_Bit_iterator::pointer)
	(_Bit_const_iterator::pointer): Define as void for C++20.
	* include/bits/stl_iterator.h (reverse_iterator::operator->()): Add
	constraints for C++20.
	(__normal_iterator::iterator_concept): Define for C++20.
	* include/bits/streambuf_iterator.h (istreambuf_iterator::pointer):
	Define as void for C++20.
	(ostreambuf_iterator::difference_type): Define as ptrdiff_t for C++20.
	(ostreambuf_iterator::ostreambuf_iterator()): Add default constructor
	for C++20.
