[JSC] Flush ProfilerSupport queue at jsc shell exit
https://bugs.webkit.org/show_bug.cgi?id=310227
rdar://172869612
Reviewed by Keith Miller.
This adds ProfilerSupport::barrierSync to flush all tasks, and in JSC shell,
we use this with std::atexit to ensure that all of Profiler tasks are
flushed before exiting. This is necessary when your JITDump has large
size and taking long time to flush for example.
