boolean binop reconstruction vs return

[nadako]

This was reduced from a more complex binop chain, but even this simple one is not packed back into a binop. Would be nice if it would ^^

class Main {
	static function main() {}

	static function f(a:Bool, b:Bool):Bool {
		return a && b;
	}
}

Main.f = function(a,b) {
	if(a) {
		return b;
	} else {
		return false;
	}
};

This looks similar to #6302

In the "real world" code this might get quite ugly:

if(this._pulsingEffect != null && (this._image != null || !this._hasImage())) {
	if(this._doAnimate) {
		if(this._animation != null) {
			return this._animation.get_animationPlaying();
		} else {
			return false;
		}
	} else {
		return true;
	}
} else {
	return false;
}

out of this source:

return _pulsingEffect != null
	&& (_image != null || !_hasImage())
	&& (!_doAnimate || (_animation != null && _animation.animationPlaying));

Reproducible with 4.0.5 and 3.4.7, so it's not a regression.
