    [diagnostics] Make basic block profiling more configurable · 7ce4b196
    Seth Brenith authored
    This change adds more granular control to the behavior that was
    previously controlled by the single flag --turbo-profiling. With this
    change, it becomes possible to:
    - output information only about builtins, ignoring functions compiled at
      runtime
    - skip the very slow process of writing the schedule and disassembly for
      all builtins, if you only want the block counts and don't need verbose
      output
    
    This change also moves the output step from Shell::OnExit to
    Isolate::DumpAndResetStats so that it's more consistent with other
    features and works in hosts other than d8.
