[svn r40] Cleaned up some of the array routines to use gep/load/store instead of memcpy/memset. Resizing arrays did not allocate enough memory for types bigger than 1 byte.

module virtcall;

class C
{
    override char[] toString()
    {
        return "overridden";
    }
}

void main()
{
    C c = new C;
    auto s = c.toString();
}
