Previously we would insert new (Arrow)FunctionExpressions as a sibling of the original function. However this would break in the outlining case as it would cause the original function expression's parent to become a SequenceExpression, breaking a bunch of assumptions in the babel plugin. To get around this, we synthesize a new VariableDeclaration to contain the newly inserted function expression and therefore insert it as a true sibling to the original function.
