I really hate those names.. what are they called in transactional memory
literature?

Also do we really need this? Using the event format stuff we could
equally well do:

{cpu/cycles/, cpu/cycles,intx/, cpu/cycles,intx_checkpointed/}

No need to push those bits through perf_event_attr::flags when you can
stuff then through perf_event_attr::config, esp. for very hardware
specific features.
