Jonathan Wakely 0d04fe4923 libstdc++: Add [[nodiscard]] to sequence containers
... and container adaptors.

This adds the [[nodiscard]] attribute to functions with no side-effects
for the sequence containers and their iterators, and the debug versions
of those containers, and the container adaptors,
