• SR-6913 Default arguments are not evaluated correctly in larger expression

Issue Description:

I've been using a custom `fatalError` that I can catch and automatically send a report to myself. Something along this:

public func XUFatalError(_ additionalInformation: String = "", file: String = #file.components(separatedBy: "/").last!, line: Int = #line, method: String = #function) -> Never {
    // Gather this and send it.
}

When this is called, the #file is incorrectly always the name of the file that contains this function - however, removing `.components(separatedBy: "/").last!`, i.e. the default argument being simply `#file` correctly passes in the file of the caller.
