We have an inner if statment (if address != target {) in one of the sides. I don't think we can move it out without making it complicated.

Adds 2 new opcodes (
TLOADandTSTORE) for manipulating state that behaves almost identically to storage but is discarded after every transaction.Adds a new opcode (
MCOPY) for copying memory. Implementing this change will be important in ensuring that the same solidity/vyper contract compiles down to the same bytecode.´Changes the behaviour of the self destruct opcode.
