The current testcase I'm trying to reduce only reproduces with IPRA enabled and requires handling multiple functions. The only real difference vs. the IR is the extra indirect to look for the underlying MachineFunction, so treat the ReduceWorkItem as the module instead of the function. The ugliest piece of this is really the ugliness of MachineModuleInfo. It not only tracks actual module state, but has a number of transient fields used for isel and/or the asm printer. These shouldn't do any harm for the use here, though they should be separated out.
