Original change's description:
> [platform][cleanup] Fix --enable-tracing
>
> The flag --enable-tracing can be used to measure how much time is spent
> in a scope. In d8 this flag did not work properly for the following
> reasons:
>
> * The tracing file is not written when the JavaScript code calls quit().
>
> * The tracing file is not written when the JavaScript code throws an
> uncaught exception, except if the --throws flag is passed to d8.
>
> The reason for these two issues is that both call Shell::Exit(), which
> end d8 immediately without calling any destructors. In addition I moved
> in a recent CL the destruction of the platform after the destruction of
> the file handle for the tracing file. Thereby the tracing file did not
> get filled with content even destructors were executed.
>
> With this CL I also call the destructors of the platform and of the file
> handle in the Shell::Exit() function. For this I make Shell::Exit()
> platform independent and let it call the platform dependent
> Shell::OSExit() at the end.
