Regarding whether to randomize macro node elimination, I find it a bit confusing that `PhaseMacroExpand` also eliminates macro nodes, perhaps it would be better to, in a separate RFE, split the phase into `PhaseMacroEliminate` and `PhaseMacroExpand`, and introduce a separate `StressMacroElimination` option and new phase names for the former?

Yes, I agree with this.
