perf tools: Make alias matching case-insensitive
Make alias matching the events parser case-insensitive. This is useful
with the JSON events. perf uses lower case events, but the CPU manuals
generally use upper case event names. The JSON files use lower case by
default too. But if we search case insensitively then users can
cut-n-paste the upper case event names.
So the following works:
% perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true
Performance counter stats for 'true':
305 BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL
0.000492799 seconds time elapsed
