I'd prefer the previous `MachineFunctionAnalysis` over this tbh, this is more verbose for no benefit, plus is still similar to `FunctionToMachineFunctionAdaptor`. I really can't think of a better name :(. I'd go back to the previous name and perhaps if we find something better in the future we can rename it.
