Commented some logging that could be '''very''' long, cuts -vv output size of a gtkd gl sample down 1.2GB by 3/4. Fixed wrong pointer type for multidimension "deep" slicing.

module typeinfo5;

void main()
{
    enum E : uint {
        A,B,C
    }
    auto ti = typeid(E);
    assert(ti.next() is typeid(uint));
    assert(ti.init is null);
}
