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 tangotests.switch2;

void main()
{
    int i=0;
    switch(i)
    {
    case 0:
        return;
    case 1:
        return;
    default:
        assert(0);
    }
}
