Sync msr-index.h to pull in recent renames of the IA32_FEATURE_CONTROL MSR definitions. Update KVM's VMX selftest and turbostat accordingly. Keep the full name in turbostat's output to avoid breaking someone's workflow, e.g. if a script is looking for the full name.
While using the renamed defines is by no means necessary, do the sync now to avoid leaving a landmine that will get stepped on the next time msr-index.h needs to be refreshed for some other reason.
No functional change intended.
