I only did a little bit of poking to get a minimum size patch, but the dependency chain and code organization of these pieces seems wrong. Can it be improved? Many of us are not using mlir-hlo as part of XLA where maybe this is tolerated, and it is counter-intuitive that the code is laid out to have such a large transitive dependency set of compiler internals just to get the top level dialect.
