2172e51246 LibJS: Implicitly break for..in loop if the RHS result is nullish
This implements the missing step 6a of 14.7.5.6 ForIn/OfHeadEvaluation:

    a. If exprValue is undefined or null, then
        i. Return Completion { [[Type]]: break, [[Value]]: empty, [[Target]]: empty }.

In other words, this should just do nothing instead of throwing during
the undefined to object coercion:

    for (const x in undefined);
