desc: Abrupt completion while getting [Symbol.iterator]
info: |
    YieldExpression: yield * AssignmentExpression

    1. Let exprRef be the result of evaluating AssignmentExpression.
    2. Let value be ? GetValue(exprRef).
    3. Let generatorKind be ! GetGeneratorKind().
    4. Let iterator be ? GetIterator(value, generatorKind).
    ...

    GetIterator ( obj [ , hint ] )

    ...
    3. If hint is async,
      a. Set method to ? GetMethod(obj, @@asyncIterator).
      b. If method is undefined,
        i. Let syncMethod be ? GetMethod(obj, @@iterator).
    ...

    GetMethod ( V, P )

    ...
    2. Let func be ? GetV(V, P).
    ...
