For example:
foo(
// `if` joins A & B
if (condition)
run { ... } // A
else
run { ... }, // B
run { ... } // C
) // `foo` unifies `A & B` and `C`, so if it is not resolved itself,
// further `if`s, `when`s, safe calls outside it, etc. continue
// building the correct type predicate until the next completed
// call.

Level of CFGNode is used to determine which call is a common one for
creating node with union of arguments (to merge flow from multiple
in-place lambdas). Before this change calls in different when branches
may have same node level, which entail passing smartcasts from moddle of
one branch to another
```
val x: Any = ...
when {
... -> run { x as String } // (1)
... -> {
run {
x.foo()
} // (2)
"hello"
}
}
```
Call `(1)` was assumed as argument of call `(2)` which is incorrect
