Compares the iterator with another iterator or a sentinel.

1) Compares an iterator with a sentinel.
If x. it_ .valueless_by_exception() is true
2-7) Compares two iterators. The != operator is synthesized from operator==
If x. it_ .valueless_by_exception() || y. it_ .valueless_by_exception() is true

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::concat_view::iterator <Const>

Parameters

x, y - iterators to compare

Return value

1)

x. it_ .index ( ) == (sizeof...(Views) - 1 ) &&
x. get-iter  <sizeof...(Views) - 1 > ( ) == get-end  <sizeof...(Views) - 1 > ( )

2) x. it_ == y. it_
3) x. it_ < y. it_
4) x. it_ > y. it_
5) x. it_ <= y. it_
6) x. it_ >= y. it_
7) x. it_ <=> y. it_
