[patch] libstdc++/58357 change std::rotate to std::_V2::rotate

[Jonathan Wakely]

DR 488 changed std:rotate to return an iterator, implemented on trunk
in r219793. To avoid problems where code expecting a non-void return
links to an instantiation of the old void-returning definition I'm
putting the new definition in the inline namespace _V2 (already used
for other entities that have changed, such as
std::condition_variable_any).

Tested x86_64-linux, committed to trunk.
