Jeffrey Wilcke 1e5725f03b core/vm: removed err checks from EVM and added snapshot to interpreter 
The REVERT op codes reverts the state by returning an error from the
instruction. The instruction was checked during in the EVM. This error
would then determine whether any gas should be consumed or not. If the
error was an errRevert, no gas was further reduced and only state was
reverted.

This solution is error prone as you'll need an err check in multiple
locations and removes the no-err check requirement of the evm. This has
been solved by passing the snapshot to the interpreter and letting the
interpreter do the state reverting if the operation so requires.
