Intel does not have guest/host-only bit in perf counters like AMD
does. To support GO/HO bits KVM needs to switch EVENTSELn values

but VMX is configured to swi
Some cpus have special support for switching PERF_GLOBAL_CTRL msr.
Add logic to detect if such support exists and works properly and extend
msr switching code to use it if available. Also extend number of generic
msr switching entries to 8.
