[PATCH] D72822: [mlir] Replace AbstractOperation::classof with a ClassID instance.

> So it seems it still might be the case that pointer can differ. D72584 <https://reviews.llvm.org/D72584> fixed this by falling back more often to the string comparison.

You are going to run into a much bigger problem given that this depends on ClassOf, which is a static `typeid` that is used pervasively across the entire code base. Making that work with shared libraries is likely the most important(difficult?) task item.
