Call postblit on a struct when appending it to an array. Use _d_arraycatnT to concatenate multiple arrays.

Browse Source 
Before, _d_arraycatT was used to concatenate multiple arrays. That caused an issue when postblit
was called on a struct multiple times. The next code asserted due to the issue:

void main()
{
    static struct S
    {
        int x;
        int pad;
        this(this)
        {
            ++x;
        }
    }

    auto sarr = new S[1];
    auto sarr2 = sarr ~ sarr ~ sarr;
    assert(sarr2[0].x == 1);
    assert(sarr2[1].x == 1);
    assert(sarr2[2].x == 1);
    assert(sarr[0].x == 0);
}
