Description
`block.difficulty` was deprecated in https://github.com/ethereum/solidity/pull/13759 and we should completely remove it in favor of `block.prevrandao`.
Contributor guide
Research direction
Search the repository for block.difficulty and block.prevrandao, then inspect the matching compiler implementation and tests. Done means Solidity 0.9.0 no longer supports block.difficulty in favor of block.prevrandao, with relevant tests updated to cover the change.
