Expand the evm standard library test

#2227 adds a basic evm test that should be expanded to test the rest of the evm library.

Note that testing for ecrecover of and EVM address (the only functionality on top of the type currently) is here:

Nice! Actually that's a good point. We don't really need a contract to test that library right? So maybe the test I added is not really needed and the logic there can just be moved into a simpler test under should_pass/stdlib/.
