    [d8] Add --stress-delay-tasks flag · 7c2aef08
    Clemens Hammacher authored
    This flag stresses different interleavings of background and foreground
    tasks by delaying the execution of each task by a random value between
    0 and 100ms (with a quadratic distribution favoring smaller delayes).
    
    The implementation is encapsulated in the new {DelayedTasksPlatform}
    class, which wraps each task in a {DelayedTask} which first sleeps for
    the given number of microseconds, then executes the actual task.
    
    Both the old {PredictablePlatform} and the new {DelayedTasksPlatform}
    are moved to the new d8-platforms.cc file with an interface to create
    them in d8-platforms.h.
