cmd/evm: added --create flag indicating the exec code is to be created
This fixes an issue if you wanted to test out code deployment rather than running a piece of code with an argument. This solves it by adding a --create flag that indicates the Create function should be used rather than the Call function. This also adds a statedb.commit call so that the proper state can be dumped when requested using the --dump flag.
