description: Variable binding is initialized to `undefined` in outer scope (IfStatement with a declaration in the first statement position in eval code)
esid: sec-functiondeclarations-in-ifstatement-statement-clauses
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.3.3.3 Changes to EvalDeclarationInstantiation

    [...]
    a. If declaredFunctionOrVarNames does not contain F, then
       i. If varEnvRec is a global Environment Record, then
          [...]
       ii. Else,
           i. Let bindingExists be varEnvRec.HasBinding(F).
           ii. If bindingExists is false, then
               i. Perform ! varEnvRec.CreateMutableBinding(F, true).
               ii. Perform ! varEnvRec.InitializeBinding(F, undefined).
