Clean up some suspicious code. There's no guarantee a constant of integer type is a ConstantInt, so it's not safe to just cast<> these to ConstantInt. (It could be a constant expression, for example) The code is shorter this way too :).

module structs2;

struct S
{
    int i;
    char c;
    S* s;
    char[4] ca;
}

void main()
{
}
