perf tools: Record events info also when :record suffix is used.
You can enable a counter's PERF_SAMPLE_RAW attribute in two fashions: - using the -R option (every counters get PERF_SAMPLE_RAW) - using the :record suffix in a trace event counter name Currently we record the events info in a trace.info file from perf record when the former method is used but we omit it with the latter. Check both situations.
