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).
