JDK-8317683 - Add JIT memory statistics
Description
When running with `-XX:CompileCommand=memstat,...,print`, we will print a final report to tty with one line per compiled method and per compiler.

But "print" also activates logging of memory costs after each individual compilation. Compiler threads may still be running and finishing last compilations when the final report is being printed, which causes those log lines to interrupt the final report.

That should be fixed.
