Proposal to include EIP-1153 in Shanghai

For this particular use case, it would be great to have it in the next hard fork.

EIP-3529 included in London is a regression for transient storage in that it greatly increased its practical gas cost. To prevent future hard forks from making transient storage significantly more expensive or breaking the use case, it's important to create these new opcodes for the specific use case of transient storage.

Arbitrum says they'd also benefit from this: https://ethereum-magicians.org/t/eip-1153-transient-storage-opcodes/553/47?u=fredlacs

We're very interested at Sealance in this, and I'm happy to help out with implementing, spec review, or whatever else needs to doing to make this a reality.

Lots of discussion about 1153 in #500
