Roman Tereshin 3054ecea3f [GlobalISel] Print/Parse FailedISel MachineFunction property ... 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.
