perf kvm: Add stat support on s390
On s390, the vmexit event has a tree-like structure: between
exit_event_begin and exit_event_end several other events may happen and
with each of them refining the previous ones.
This patch adds a decoder for such events to the generic code and also
the files <asm/kvm_perf.h> and kvm-stat.c for s390.
Commands 'perf kvm stat record', 'report' and 'live' are supported.
