When the user enables UL -Xlog:perf+datacreation=debug, it may crash in PerfDataManager::destroy().

The following line will crash when _sample is NULL.
  log_debug(perf, datacreation)("Total = %d, Sampled = %d, Constants = %d",
                                _all->length(), _sampled->length(), _constants->length());

This only happens when UsePerfData is on and PerfDataManager::destroy() is invoked before StatSampler::initialize() which initializes PerfDataManager::_sampled.
PerfDataManager::destroy() is called by VM_Exit which can be triggered by SIGINT on Linux anytime.

A reproducible: invoke the following command and keep pressing Ctrl-c.
$perf stat -r 100 java -Xlog:perf+datacreation=debug --version
