This EIP adds an opcode that returns the current chain's EIP-155 unique identifier.
## Motivation
[EIP-155](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-155.md) proposes to use the chain ID to prevent replay attacks between different chains. It would be a great benefit to have the same possibility inside smart contracts when handling signatures, especially for Layer 2 signature schemes using [EIP-712](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md).

## Specification
Adds a new opcode `CHAINID` at 0x46, which uses 0 stack arguments. It pushes the current chain ID onto the stack. Chain ID is a 256-bit value. The operation costs `G_base` to execute.
