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.

Resolving Keccak-256: check if arguments are identifiers early.
...
Previously, the check on whether the optimization was useful gas wise was done before checking if
the keccak256 opcode had identifier as arguments. Since the gas meter crashes when encountering
certain Yul opcodes (create, dataoffset, etc.), this optimizer step crashed.
