	* sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h (pthread_cond_t):
	Add __data.__futex field, reshuffle __data.__clock.
	* sysdeps/unix/sysv/linux/sh/pthread_cond_signal.S
	(__pthread_cond_signal): Increment __futex at the same time as
	__wakeup_seq or __total_seq.  Pass address of __futex instead of
	address of low 32-bits of __wakeup_seq to futex syscall.
	* sysdeps/unix/sysv/linux/sh/pthread_cond_wait.S
	(__pthread_cond_wait): Likewise.  Pass __futex value from before
	releasing internal lock to FUTEX_WAIT.
	* sysdeps/unix/sysv/linux/sh/pthread_cond_timedwait.S
	(__pthread_cond_timedwait): Likewise.
	* sysdeps/unix/sysv/linux/sh/pthread_cond_broadcast.S
	(FUTEX_CMP_REQUEUE): Define.
	(__pthread_cond_broadcast): Set __futex to 2 * __total_seq.
	Use FUTEX_CMP_REQUEUE operation instead of FUTEX_REQUEUE.
	Pass __futex value from before the unlock and __futex address instead
	of address of low 32-bits of __wakeup_seq to futex syscall.
	Fallback to FUTEX_WAKE all on any errors.
