Subject[PATCH 7/7] perf test: Parse events break apart tests
From
Break multiple tests in the main test into individual test cases. Make
better use of skip and add reasons. Skip also for parse event permission
issues (detected by searching the error string). Rather than break out
of tests on the first failure, keep going and logging to pr_debug.
