perf stat: Print cache misses as percentage
Before:
113,393,041 cache-references # 83.636 M/sec
7,052,454 cache-misses # 5.202 M/sec
After:
112,589,441 cache-references # 87.925 M/sec
6,556,354 cache-misses # 5.823 %
misses/hits percentages are more expressive than absolute numbers
or rates.
(Also prettify the CPUs printout line to not have a trailing whitespace.)
