Please review the following small patch.

bug: https://bugs.openjdk.java.net/browse/JDK-8025277
webrev: http://cr.openjdk.java.net/~anoll/8025277/webrev.00/

I added the diagnostic VM option PrintMethodFlushingStatistics to print
statistics about the NMethodSweeper (sweep times) on exit. This is useful
to determine performance bottlenecks of applications that heavily compile
code (e.g. nashorn).

Thanks in advance!

Best regards,

By the way, I'm Tobias Hartmann, a student from Switzerland currently
working on my Master Thesis "Code Cache Optimizations for Dynamically
Compiled Languages" on supervision of Albert Noll.
