An object typed T through out parameter is initialized by T.init (like memcpy),
but its destructor is not called before initializing.

----
int dtor_cnt;
struct S
{
    int n;
    ~this(){ dtor_cnt++; }
}
void test1()
{
    void f1(out S s){}

    S s = S(1);
    dtor_cnt = 0;
    f1(s);
    assert(dtor_cnt == 1);  // NG
}
void test2()
{
    void f2(out S[2] sa){}

    S[2] sa = [S(1), S(2)];
    dtor_cnt = 0;
    f2(sa);
    assert(dtor_cnt == 2);  // NG
}
void main()
{
    test1();
    test2();
}
