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 the first statement position in the global scope)

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]
