    The following rules for IfStatement augment those in 13.6:

    IfStatement[Yield, Return]:
        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else Statement[?Yield, ?Return]
        if ( Expression[In, ?Yield] ) Statement[?Yield, ?Return] else FunctionDeclaration[?Yield]
        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield] else FunctionDeclaration[?Yield]
        if ( Expression[In, ?Yield] ) FunctionDeclaration[?Yield]
