description: Variable binding is left in place by legacy function hoisting. CreateGlobalVariableBinding leaves the binding as non-enumerable even if it has the chance to change it to be enumerable. (IfStatement with a declaration in both statement positions in the global scope)
esid: sec-functiondeclarations-in-ifstatement-statement-clauses
flags: [generated, noStrict]
includes: [fnGlobalObject.js, propertyHelper.js]
info: |
    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]
