Currently associative arrays are compared by comparing its `impl` pointers e.g.
`aa1 < aa2` is rewritten as `cast(void*) aa1 > cast(void*) aa2` instead of
calling a runtime function.

---
void main()
{
    int[int] aa1 = [0: 1];
    int[int] aa2 = [0: 1];
    assert(aa1 == aa2); // Passes
    assert(!(aa1 < aa2) && !(aa1 > aa2)); // Fails, different `impl`-s
}
---

And yes, there is not such function in druntime so this is druntime's issue
too.
