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);
