[PATCH 2/2] Fix perf-hooks test

From: Numfor Mbiziwo-Tiapo
Date: Tue Jul 02 2019 - 13:37:27 EST


The perf-hooks test fails with Address Sanitizer and Memory
Sanitizer builds because it purposefully generates a segfault.
Checking if these sanitizers are active when running this test
will allow the perf-hooks test to pass.
