description: Variable binding is initialized to `undefined` in outer scope (IfStatement with a declaration in both statement positions in function scope)
esid: sec-functiondeclarations-in-ifstatement-statement-clauses
es6id: B.3.4
flags: [generated, noStrict]

    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]


    B.3.3.1 Changes to FunctionDeclarationInstantiation

    [...]
    2. If instantiatedVarNames does not contain F, then
       a. Perform ! varEnvRec.CreateMutableBinding(F, false).
       b. Perform varEnvRec.InitializeBinding(F, undefined).
       c. Append F to instantiatedVarNames.
