+ * include/bits/ranges_algo.h (__lexicographical_compare_fn):
+ Also check that the iterator and sentinel have the same type before
+ applying the unwrapping optimization for __normal_iterator.
+ Split the check into two, one for the first iterator/sentinel
+ pair and another for second iterator/sentinel pair. Remove uses
+ of __niter_base, and remove uses of std::move on a
+ __normal_iterator.
+ * include/bits/ranges_algobase.h (__equal_fn): Likewise.
+ (__copy_or_move): Likewise. Perform similar adjustments for
+ the reverse_iterator and move_iterator optimizations. Inline
+ the checks into the if-constexprs, and use using-declarations to
+ make them less visually noisy. Remove uses of __niter_wrap.
+ (__copy_or_move_backward): Likewise.
