Was good idea, but with C++ types with constructor/destructor, was getting in
the way as compiler was destructing those items where it was not desired.
Since C++ does not allow zero-sized arrays, just remove it...
Newer compilers / language allows structs with constructor in union.
So, this was not actually testing anything. Indeed, the recent
change in DISALLOW_COPY *is* making some of our types non-POD.
That broke some bots.
Just remove this since it wasn't doing much, and I'd rather have
DISALLOW_COPY.
