Daniel Gibson 02f49e55bf Suppress GCC8+ warnings about memcpy()/memset() on classes 
.. with "no trivial copy-assignment".
All the cases I checked were harmless; as long as a class has no vptr
or owns memory (or other resources) that need to be handled properly
in the destructor, memcpy() and memset() aren't too dangerous.
