perf stat: Improve output
Increase size for event name to handle bigger names like
'L1-d$-prefetch-misses'
Changed scaled counters from percentage to a multiplicative
factor because the latter is more expressive.
Also aligned the scaling factor, otherwise sometimes it looks
like:
384 iTLB-load-misses (4.74x scaled)
452029 branch-loads (8.00x scaled)
5892 branch-load-misses (20.39x scaled)
972315 iTLB-loads (3.24x scaled)
Before:
150708 L1-d$-stores (scaled from 23.57%)
428804 L1-d$-prefetches (scaled from 23.47%)
314446 L1-d$-prefetch-misses (scaled from 23.42%)
252626137 L1-i$-loads (scaled from 23.24%)
5297550 dTLB-load-misses (scaled from 23.96%)
106992392 branch-loads (scaled from 23.67%)
5239561 branch-load-misses (scaled from 23.43%)
After:
1731713 L1-d$-loads ( 14.25x scaled)
44241 L1-d$-prefetches ( 3.88x scaled)
21076 L1-d$-prefetch-misses ( 3.40x scaled)
5789421 L1-i$-loads ( 3.78x scaled)
29645 dTLB-load-misses ( 2.95x scaled)
461474 branch-loads ( 6.52x scaled)
7493 branch-load-misses ( 26.57x scaled)
