libstdc++: Add noexcept to some std::counted_iterator operations
This was inspired by LWG 4245 but goes further. Anything which only
reads or writes the _M_length member can be noexcept. That
member is an iterator difference_type which means it's a signed integer
type or the __max_diff_type integer-like class type, so all arithmetic
and comparisons are non-throwing.
libstdc++-v3/ChangeLog:
* include/bits/stl_iterator.h (counted_iterator): Add noexcept
to friend operators which only access the _M_length member.
