    libpmc: Prefer fixed counters in Intel event aliases.
    
    It is recommended by Intel to use fixed counters when possible to
    leave programmable ones for different events.
    
    This fixes `pmc stat`, which tries to count 6 events same time, while
    many Intel CPUs have only 4 programmable counters.
