It expects two stack items, the top item is the `memory_length` followed by `memory_offset`. Both of these can equal to zero. The cost of the `REVERT` instruction equals to that of the `RETURN` instruction. It expects two stack items, the top item is the `memory_offset` followed by `memory_length`.

In case there is not enough gas left to cover the cost of `REVERT` or there is a stack underflow, the effect of the `REVERT` instruction will equal to that of a regular out of gas exception.
