Mikhail Glukhikh 5723c2a077 Front-end fix: result type corrected for increment / decrement expressions. Smart cast allowed on a postfix increment result. See KT-7561.
Now result type is receiver type for postfix increment, or increment result type for prefix increment.
A set of relevant tests.

class MyClass

fun MyClass?.inc(): MyClass? { return null }
public fun box() {
var i : MyClass?
i = MyClass()
// type of j should be MyClass?
var j = ++i
// j is null so call should be unsafe
j<!UNSAFE_CALL!>.<!>hashCode()
