	PR libstdc++/39909
	* include/std/mutex (__get_once_functor_lock, __get_once_mutex,
	__set_once_functor_lock_ptr): Replace global lock object with local
	locks on global mutex.
	* src/mutex.cc (__get_once_functor_lock, __get_once_mutex,
	__set_once_functor_lock_ptr): Likewise, keeping old function to
	preserve ABI.
	(__once_proxy): Use pointer to local lock if set, global lock
	otherwise.
	* config/abi/pre/gnu.ver: Add new symbols to new ABI version.
	* testsuite/util/testsuite_abi.cc: Add GLIBCX_3.4.12 version.
	* testsuite/30_threads/call_once/39909.cc: New.
