Jin Yao reported issue with possible conflict between raw
events and term values in pmu event syntax.
Currently following syntax is resolved as raw event with
instead of using 'read' term from uncore_imc_free_running pmu,
because 'read' is correct raw event syntax with 0xead value.
To solve this issue we do following:
- check existing terms during rXXXX syntax processing
and make them priority in case of conflict
- allow pmu/r0x1234/ syntax to be able to specify conflicting
raw event (implemented in previous patch)
Also adding automated tests for this and perf_pmu__parse_cleanup
call to parse_events_terms, so the test gets properly cleaned up.
