7/// * EOFCREATE opcode
8/// * Creation transaction.
9///
10/// Creation transaction uses initdata and packs EOF and initdata inside it,
11/// and this eof bytecode needs to be validated.
12///
13/// Opcode creation uses already validated EOF bytecode, and input from Interpreter memory.
14///
15/// Address is already known and is passed as an argument.
