Original change's description:
> [debug] introduced runtime side effect check
>
> This CL demonstrates minimum valuable addition to existing debug evaluate
> without side effects mechanism.
> With this CL user can evaluate expressions like:
> [a,b] // create any kind of temporary array literals
> [a,b].reduce((x,y) => x + y, 0); // use reduce method
> [1,2,3].fill(2); // change temporary arrays
>
> The core idea: any change of the object created during evaluation without
> side effects is side effect free. As soon as we try to store this temporary
> object to object existed before evaluation we will terminate execution.
>
> Implementation:
> - track all objects allocated during evaluation and mark them as temporary,
> - patch all bytecodes which change objects.
>
> A little more details (including performance analysis): [1].
