Constantinople statetest support

[holiman]

Version

Version: parity-evm built from scratch today, so most likely bbaac0c

Description

I trying out the fuzzer on Constantinople rules, which unfortunately does not execute on parity.
parity:

# /parity-evm state-test --std-json /testfiles/martin-Sat_21_41_37-29930-11-test.json

{"action":"skipping because of missing spec","test":"randomStatetestmartin-Sat_21_41_37-29930-11:constantinople:0"}

geth

# evm --json --nomemory statetest /testfiles/martin-Sat_21_41_37-29930-11-test.json

Example file to repro the behaviour (I had to remove the code due to max-character limit in GH issues):

This is one of the few remaining snags before we can put fuzzing properly into prod.
