Fixed accumulation of run time for processes that don't accumulate
any statclock ticks. Pretend that all the time up to the first
statclock tick is system time. . This makes a difference mainly for
benchmarks that test short-lived processes - the user and system
times for processes that each lived for about 1ms only added up to
about 10% of the real time even when there was very little interrupt
activity.
Break the printing of a quad_t variable correctly.
