perf tools: Accept case-insensitive symbolic event variants
We currently fail on something like '-e CPU-migrations', with: invalid or unsupported event: 'CPU-migrations' While 'CPU-migrations' is how we actually print out the event in the default perf stat output: Performance counter stats for 'true': 0.202204 task-clock-msecs # 0.282 CPUs 0 context-switches # 0.000 M/sec 0 CPU-migrations # 0.000 M/sec So change the matching to be case-insensitive.
