29041c8101 Remove ReasoningBasedSimplifier from libyul 
Due to a design decision to move away from a bundled SMT solver,
ReasoningBasedSimplifier in its current form cannot be use any longer.
This is a necessary step to allow a unified way to call solvers using
only SMTLIB interface.

Since this optimization pass has always been marked as highly
experimental and never turned on by default, it should be OK to remove
it.

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.
