core/vm, tests: update tests, enable constantinople statetests, fix SAR opcode (#17538)
This commit does a few things at once: - Updates the tests to contain the latest data from ethereum/tests repo. - Enables Constantinople state tests. This is needed to be able to fuzz-test the evm with constantinople rules. - Fixes the error in opSAR that we've known about for some time. I was kind of saving it to see if we hit upon it with the random test generator, but it's difficult to both enable the tests and have the bug there -- we don't want to forget about it, so maybe it's better to just fix it.
