2cdd3b2081 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.

b599235b8d Skip resolving Keccak if AST contains msize.
Also a refactoring changing `m_optimizeMLoad` to `m_containsMSize`.
