x86, sched_clock(): mark variables read-mostly
Impact: micro-optimization
There's a number of variables in the sched_clock() path that are
in .data/.bss - but not marked __read_mostly. This creates the
danger of accidental false cacheline sharing with some other,
write-often variable.
So mark them __read_mostly.
