re PR libgomp/51298 (libgomp team_barrier locking failures)
PR libgomp/51298
* config/linux/bar.h: Use atomic rather than sync builtins.
* config/linux/bar.c: Likewise. Add missing acquire
synchronisation on generation field.
* task.c (gomp_barrier_handle_tasks): Regain lock so as to not
double unlock.
