    REGRESSION (r50218-r50262): E*TRADE accounts page is missing content

    The logic for flagging that a structure has non-enumerable properties
    was in addPropertyWithoutTransition, rather than in the core Structure::put
    method.  Despite this I was unable to produce a testcase that caused
    the failure that etrade was experiencing, but the new assertion in
    getEnumerablePropertyNames triggers on numerous layout tests without
    the fix, so in effecti all for..in enumeration in any test ends up
    doing the required consistency check.
