Improve trace logs in safepoint machinery

XMLWordPrintable

      During the performance investigations in safepoint machinery (notably JDK-8350324), I found the trace logging lacking. It would be good to improve it in order to finely profile various microscopic things like thread list walks, the blocking/resuming of Java threads, etc.
