Provided overload to TypeClass::builtinTypeInfo to return true. Shouldn't almost all types have a builtin typeinfo? Maybe it'd be better to have the default at true and only overload typedef and friends.

module typeinfo11;

void main()
{
    int[4] a;
    TypeInfo ti;
    ti = typeid(typeof(a));
    assert(ti.next() is typeid(int));
    assert(ti.tsize() == 16);
}
