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 aa2;

void main()
{
    long[float] aa;
    long* p = 2.0f in aa;
    assert(!p);
    aa[4f] = 23;
    p = 4f in aa;
    assert(p);
    assert(*p == 23);
}
