Subject: [PATCH] IR: defaults: calculate right `this` dispatch receiver
 parameter.

previously in case:
```
fun box(): String {
    val a: A = B(1)
    a.copy(1)
    a.component1()
    return "OK"
}

interface A {
    fun copy(x: Int): A
    fun component1(): Any
}

data class B(val x: Int) : A
```

in stab `B::copy$default` `B::copy` called with `A::this` that behaviour isn't correct, should be `B::this` used.
