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.3.3.1 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.
