libstdc++: Restore unconditional atomic load in COW std::string
The relaxed load is already optimal, checking the __single_threaded
global before doing a non-atomic load isn't an optimization.
libstdc++-v3/ChangeLog:
* include/bits/cow_string.h (basic_string::_M_is_leaked()):
Revert change to check __is_single_threaded() before using
atomic load.
