    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].
