    libpmc: add armv8 pmu-event aliases
    
    These are all "standard microarchitectural events", which in theory are
    supported by every ARMv8 processor. In practice, it depends on the
    pmu-event definitions being complete and accurate, which they are not
    for every processor. Still, these aliases should be functional on the
    majority of systems.
