    Support the PowerPC architecture using the ins_ops association
    method.
    
    Committer notes:
    
    Testing it with a perf.data file collected on a PowerPC machine and
    cross-annotated on a x86_64 workstation, using the associated vmlinux
    file:
    
    $ perf report -i perf.data.f22vm.powerdev --vmlinux vmlinux.powerpc
