Failing test highlighting no poisoning if dtor undeclared. 

Summary:
If class or struct has not declared a destructor,
no destructor is emitted, and members are not poisoned
after destruction. This case highlights bug in current
implementation of use-after-dtor poisoning (detailed
in https://github.com/google/sanitizers/issues/596).

Only check simplest object for existence of sanitizing callback.

Rename test.
