perf tools: Enable config and setting names for legacy cache events
This patch allows setting config terms for legacy cache events.
For example:
# perf stat -e L1-icache-misses/name=valA/ -e branches/name=valB/ ls
...
Performance counter stats for 'ls':
11299 valA
451605 valB
0.000779091 seconds time elapsed
# perf record -e cache-misses/name=inh/ -e cache-misses/name=noinh,no-inherit/ bash
# ls
# exit
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.023 MB perf.data (131 samples) ]
# perf report --stdio | grep -B 1 'Event count'
# Samples: 105 of event 'inh'
# Event count (approx.): 109118
--
# Samples: 26 of event 'noinh'
# Event count (approx.): 48302
A test case is introduced to test this feature.
