Assignments in the condition of an if statements don't store the promoted information (for the write of that variable). This fix stores the promotion of that expression for when we use it to null check or otherwise. Part 1 because there's still some holes with postfix operators and null asserts that need to be fixed, but this behaviour stands on its own at the moment. Everything is behind the flag so we'll iterate.
