`TypeInfo_AC` is a `TypeInfo` sometimes (see Issue 12303) used for arrays of
classes or interfaces. But it isn't designed to work with interfaces, so we
have wrong code e.g. here:
---
interface I { }
class C: I { }

void main()
{
    I[] a = [new C];
    int[I[]] aa = [a : 0];
    assert(a in aa); // fails
}
