    identifier. Delete unused (and now incorrect) function IsValidStrictVariable.
    
    Implements the strong mode proposal's static restrictions on the use of the
    identifier 'undefined'. Assumes these restrictions are intended to be identical
    to the restrictions on the use of 'eval' and 'arguments' in strict mode. The
    AllowEvalOrArgumentsAsIdentifier enum has been renamed to
    AllowRestrictedIdentifiers as logic involving it is now also used for this case.
