When we get a report like

==== Test Assertion Failure ====
  x86_64/state_test.c:157: run->exit_reason == KVM_EXIT_IO
  pid=955 tid=955 - Success
     1	0x0000000000401350: main at state_test.c:154
     2	0x00007fc31c9e9412: ?? ??:0
     3	0x000000000040159d: _start at ??:?
  Unexpected exit reason: 8 (SHUTDOWN),

it is not obvious which particular stage failed. Add the info.

7edcb73433 KVM: selftests: Add hyperv_cpuid test
Add a simple (and stupid) hyperv_cpuid test: check that we got the
expected number of entries with and without Enlightened VMCS enabled
and that all currently reserved fields are zeroed.

1e7ecd1b3d KVM: selftests: state_test: test bare VMXON migration
Split prepare_for_vmx_operation() into prepare_for_vmx_operation() and
load_vmcs() so we can inject GUEST_SYNC() in between.

fff8dcd7b4 kvm: selftests: port dirty_log_test to aarch64
While we're messing with the code for the port and to support guest
page sizes that are less than the host page size, we also make some
code formatting cleanups and apply sync_global_to_guest().

eabe7881d2 kvm: selftests: tidy up kvm_util
Tidy up kvm-util code: code/comment formatting, remove unused code,
and move x86 specific code out. We also move vcpu_dump() out of
common code, because not all arches (AArch64) have KVM_GET_REGS.
