Adds support for the EVM version "Paris".
Deprecates `block.difficulty` and disallow `difficulty()` in inline assembly for EVM versions >= paris.
The change is due to the renaming introduced by EIP-4399 (see: https://eips.ethereum.org/EIPS/eip-4399).
Introduces `block.prevrandao` in Solidity and `prevrandao()` in inline assembly for EVM versions >= paris.

Merge pull request #13709 from ChrisXXXXXXX/patch-2
Separate node for every `if` and `case` body in the Yul CFG

feade14fd6 Update ControlFlowSideEffectsCollector.cpp
There are errors in the function void ControlFlowBuilder::operator()(If const& _if) and function void ControlFlowBuilder::operator()(Switch const& _switch) when calculating CFG.
1. In the function void ControlFlowBuilder::operator()(If const& _if), the if.condion block is not the same block as the if.then block. The original code is calculated as one same block.
2. The switch.expression block are not the same block as all the cases block in cases, the original code is calculated as one same block.
This can cause some potential problems during the optimization phase.
