[analyzer] Fix trivial copy for empty objects.
The SVal for any empty C++ object is an UnknownVal. Because RegionStore does
not have binding extents, binding an empty object to an UnknownVal may
potentially overwrite existing bindings at the same offset.
Therefore, when performing a trivial copy of an empty object, don't try to
take the value of the object and bind it to the copy. Doing nothing is accurate
enough, and it doesn't screw any existing bindings.
