Subject[PATCH v2] perf tools: make -C consistent across commands (for cpu list arg)
Date
Currently the meaning of -C varies by perf command: for perf-top,
perf-stat, perf-record it means cpu list. For perf-report it
means comm list. Then perf-annotate, perf-report and perf-script
use -c for cpu list.

Fix annotate, report and script to use -C for cpu list to be
consistent with top, stat and record. This means report needs
to use -c for comm list which does introduce a backward
compatibility change.

v1 -> v2
- update perf-script.txt too
