Test SetCode authorization combined with a recipient SSTORE.

The authority (an existing EOA) gains a fresh delegation, charged the top-frame AUTH_BASE; the called recipient then performs an SSTORE whose regular and state costs are charged during execution. The header gas_used is the max of the regular block and the (AUTH_BASE + SSTORE) state block.
