Add a define for PRED_CMD_IBPB and use it to replace the open coded '1' in

What does nVMX mean here?

Nested VMX.  From KUT's perspective, the testing exists to validate KVM's nested
VMX implementation.  If it's at all confusing, I'll drop the 'n'  And we've already
established that KUT can be used on bare metal, even if that's not the primary use
case.

So vmexit.flat is supposed to be ran in L1 VM?

I'm confused and interested in how KUT is used on bare metal.
