          MCE: Relay UCR MCE to guest
      
          UCR (uncorrected recovery) MCE is supported in recent Intel CPUs,
          where some hardware error such as some memory error can be reported
          without PCC (processor context corrupted). To recover from such MCE,
          the corresponding memory will be unmapped, and all processes accessing
          the memory will be killed via SIGBUS.
      
          For KVM, if QEMU/KVM is killed, all guest processes will be killed
          too. So we relay SIGBUS from host OS to guest system via a UCR MCE
          injection. Then guest OS can isolate corresponding memory and kill
          necessary guest processes only. SIGBUS sent to main thread (not VCPU
          threads) will be broadcast to all VCPU threads as UCR MCE.

      The bug is that env->stopped is not really as comprehensive as it seems to
      be (and cpu_has_work thinks); it is only valid with iothread basically,
      and even then it is cleared by reset and it is not set when starting
      qemu with -S.
