Description
The optimized build fails with:

internalVMTests.o: In function `InternalVMTests::run()':
/oracle/full_jdk_build/hotspot/src/share/vm/utilities/internalVMTests.cpp:127: undefined reference to `test_memset_with_concurrent_readers()'
collect2: error: ld returned 1 exit status

JDK-8131330 removed the NOT_DEBUG_RETURN declaration for the unit test 'test_memset_with_concurrent_readers()'. To be available in the optimized build, it should be guarded by ASSERT:
