Lisa Hsu b8082eb508 lift system-independent binning stuff out of Tru64System into System.
kern/tru64/tru64_system.cc:
    make binned_fns a parameter for System in addition to Tru64System.  Do all the fnEvents setting at the System level, since that is system-independent.
kern/tru64/tru64_system.hh:
    deal with FnEvents in the System, and move some fns over to System.
sim/system.cc:
sim/system.hh:
    lift binning stuff into System out of Tru64System
