    [foozzie] Compare baseline/default in every run · cca29094
    Michael Achenbach authored
    Previously we ran baseline (e.g. ignition) and one random secondary
    comparison configuration (e.g. turbofan) from the list of experiments.
    But Clusterfuzz imposes limitations on the total amount of fuzz tests.
    Therefore this change enables more throughput by always running the
    default configuration (ignition_turbofan like V8 is shipped)
    additionally to the baseline and the secondary configuration.
    
    This, hence, doubles the number of comparisons we run, with less than
    50% additional runtime, since the slow baseline configuration is only
    run once.
    
    The experiments table is updated accordingly. Explicit entries running
    ignition_turbofan are removed (as it always runs now), instead some
    of the other configurations are increased in their relative
    percentage. We also get a few new configurations that didn't run
    before (e.g. forcing the slow path on x86).
