Event parsing was recently refactored:
https://lore.kernel.org/all/20230502223851.2234828-1-irogers@google.com/

During these changes I wanted to get coverage of all parts of the
parse-events.y and found that I couldn't test the array code.

The first patch fixes a BPF testing issue.
The 2nd and 3rd patch remove the BPF array event parsing code so that
it isn't adding complexity to event parsing.

Ian Rogers (3):
  perf parse-event: Avoid BPF test segv
  perf tools: Revert enable indices setting syntax for BPF map
  perf parse-events: Remove array remnants
