8/// EOF create can be called from two places:
9/// * EOFCREATE opcode
10/// * Creation transaction.
11///
12/// Creation transaction uses initdata and packs EOF and initdata inside it,
13/// and this eof bytecode needs to be validated.
14///
15/// Opcode creation uses already validated EOF bytecode, and input from Interpreter memory.
16///
17/// Address is already known and is passed as an argument.
