Parts of a 'perf kvm stat' code make sense only for x86.
Let's move this code into the arch/x86/kvm-stat.c file and add
util/kvm-stat.h for generic structure definitions.
Add a global array 'kvm_reg_events_ops' for accessing the
arch-specific 'kvm_events_ops' from generic code.
Since the several global arrays (i.e. 'kvm_events_tp') have been moved
to arch/*, we can not know their sizes and use them directly in
builtin-kvm.c. This patch fixes that problem by adding trimming
NULL element to each array and changing the behavior of their handlers
in generic code.
