Changes:
v4 -> v5:
* Fix the building errors with configuration options "--arch=i386" or
"--enable-efi' introduced by v4 patch "Add IBPB indirect jump asm
blob" (Patch 15/18)
* Add patch 18/18 to print count details if test case fails

All changes pass validation on Intel Sapphire Rapids and Emerald Rapids
platforms against latest kvm-x86/next code (0ce958282e66). No tests on
AMD platforms since no AMD platform on hand. Any tests on AMD platform
are appreciated.
