Heiko Carstens 5c9e37e523 s390/preempt: Optimize __preempt_count_dec_and_test() 
Use __atomic_add_const_and_test() within __preempt_count_dec_and_test().
With this it is possible to decrease preempt_count by one and test if
need_resched is set with one instruction, if the compiler has support for
flag output operand constraints.
