### Specification
Adds a new opcode at 0xf5, which takes 4 stack arguments: endowment, memory_start, memory_length, salt. Behaves identically to CREATE, except using `sha3(msg.sender ++ salt ++ init_code)[12:]` instead of the usual sender-and-nonce-hash as the address where the contract is initialized at.

#### Option 2
Use `sha3(0xff ++ msg.sender ++ salt ++ init_code)[12:]`
Use `keccak256(0xff ++ msg.sender ++ salt ++ init_code)[12:]`
Rationale: ensures that addresses created with this scheme cannot collide with addresses created using the traditional `sha3(rlp([sender, nonce]))` formula, as 0xff can only be a starting byte for RLP for data many petabytes long.
