When allocating for an array, only the last dimension will have D-array
semantics, with capacity info. When allocating an array via new, ALL dimensions
should have appendable info associated.

void main()
    alias T0 = ushort;
    auto s0 = new T0[](10);
    assert(s0.capacity); //OK

    alias T1 = ushort;
    auto s1 = new T1[][](10, 10);
    foreach (e; s1)
        assert(e.capacity); //OK
    assert(s1.capacity);    //FAILS

    alias T2 = ushort[];
    auto s2 = new T2[][](10, 10);
    foreach (e; s2)
        assert(e.capacity); //OK
    assert(s2.capacity);    //FAILS

    alias T3 = ushort;
    auto s3 = new T3[][][](10, 10, 10);
    foreach (e; s3)
        foreach (ee; e)
            assert(ee.capacity); //OK
        assert(e.capacity);      //FAILS
    assert(s2.capacity); //FAILS

All the above "FAILS" should pass.
