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.
