gcc:
	* ginclude/stdatomic.h: Reformat contents of file.  Include macro
	names in names of local temporaries.
	(memory_order): Do not use enum tag.
	(atomic_init): Use do { } while (0).
	(atomic_thread_fence, atomic_signal_fence): Make function-like
	macros.
	(atomic_is_lock_free): Pass object pointer to
	__atomic_is_lock_free.
	(__atomic_type_lock_free): New macro.
	(ATOMIC_BOOL_LOCK_FREE, ATOMIC_CHAR_LOCK_FREE)
	(ATOMIC_CHAR16_T_LOCK_FREE, ATOMIC_CHAR32_T_LOCK_FREE)

	(ATOMIC_INT_LOCK_FREE, ATOMIC_LONG_LOCK_FREE)
	(ATOMIC_LLONG_LOCK_FREE, ATOMIC_POINTER_LOCK_FREE): Define using
	__atomic_type_lock_free.
	(atomic_load_explicit): Use given memory order, not
	__ATOMIC_SEQ_CST.
	(atomic_exchange_explicit): Use __atomic_exchange with pointer to
	temporary for value.
	(atomic_compare_exchange_strong_explicit)
	(atomic_compare_exchange_weak_explicit): Use
	__atomic_compare_exchange.
	(atomic_flag): Make into a structure type.
	(ATOMIC_FLAG_INIT): Use braced initializer.
	(atomic_flag_test_and_set, atomic_flag_test_and_set_explicit): Use
	__atomic_test_and_set.
	(atomic_flag_clear, atomic_flag_clear_explicit): Use
	__atomic_clear.
