FailedISel MachineFunction property is part of the CodeGen pipeline state as much as every other property, notably, Legalized, RegBankSelected, and Selected. Let's make that part of the state also serializable / de-serializable, so if GlobalISel aborts on some of the functions of a large module, but not the others, it could be easily seen and the state of the pipeline could be maintained through llc's invocations with -stop-after / -start-after. To make MIR printable and generally to not to break it too much too soon, this patch also defers cleaning up the vreg -> LLT map until ResetMachineFunctionPass. To make MIR with FailedISel: true also machine verifiable, machine verifier is changed so it treats a MIR-module as non-regbankselected and non-selected if there is FailedISel property set.
