Lets keep this similar to LLVM's equvalent pass (given inspiration and reuse)

/// This file implements the IRNormalizer class which aims to transform MLIR
/// inputs into a normal form by reordering and renaming instructions while
/// preserving the same semantics. The normalizer makes it easier to spot
/// semantic differences while diffing two modules which have undergone
/// different passes.
