TSTORE bug #1

This example builds a testcase for https://github.com/ethereum/execution-specs/issues/917

The bug is pretty subtle, it pertains to T-storage inside contract deployments.

1. a: Run a CREATE2
2. b: In the initcode, SSTORE(slot:1, value:1)
3. b: Return too large bytecode, thus failing the creation
4. a: Run the CREATE2 again
5. b: check SLOAD(slot:1). If this is non-zero, we have hit the bug.

The testcase implements one way of doing it.

Finished testcase: [./tstore_test-2.json]
