This change allows function literals in invocations to be inferred in
dependency order. For example, given the following code:
U f<T, U>(T Function() g, U Function(T) h) => h(g());
test() {
var x = f(() => 0, (y) => [y]);
}
The function literal `() => 0` is inferred first, causing the type
parameter `T` to be assigned the type `int`. Then, `(y) => [x]` is
inferred with the benefit of this type assignment, so `y` gets the
type `int`, and consequently, `U` gets assigned the type `List<int>`.
This completes the support for
https://github.com/dart-lang/language/issues/731 (improved inference
for fold etc.)
