To support XSAVES system states, change some names to distinguish
user and system states.

I don't understand what the logic here is. SDM says:

XSAVES—Save Processor Extended States Supervisor

the stress being on "Supervisor" - why does it need to be renamed to
"system" now?

Good point.  However, "system" is more indicative; CET states are per-task and
not "Supervisor".  Do we want to go back to "Supervisor" or add comments?
