perf tools: Add hardcoded name term for pmu events
Adding a new hardcoded term 'name' allowing to specify a name for the
pmu event. The term is defined along with standard pmu terms. If no
'name' term is given, the event name follows following template:
"raw 0x<perf_event_attr::config>"
running:
perf stat -e cpu/config=1,name=krava1/u ls
will produce following output:
...
Performance counter stats for 'ls':
0 krava1
...
running:
perf stat -e cpu/config=1/u ls
will produce following output:
...
Performance counter stats for 'ls':
0 raw 0x1
...
