The only possible kind of a conversion in initialization of a shared
pointer to an array is a qualification conversion (i.e., adding
cv-qualifiers). This patch adds tests for converting from `A[]` to
`const A[]` to the following functions:

  template<class Y> explicit shared_ptr(Y* p);
  
  template<class Y> shared_ptr(const shared_ptr<Y>& r);
  template<class Y> shared_ptr(shared_ptr<Y>&& r);
  
  template<class Y> shared_ptr& operator=(const shared_ptr<Y>& r);
  template<class Y> shared_ptr& operator=(shared_ptr<Y>&& r);
  
  template<class Y> void reset(Y* p);
  template<class Y, class D> void reset(Y* p, D d);
  template<class Y, class D, class A> void reset(Y* p, D d, A a);

Similar tests for converting functions that involve a `weak_ptr` should
be added once LWG issue 3001 <https://cplusplus.github.io/LWG/issue3001>
is implemented.
