RFR 8207689: Remove the vm options which are expiring in JDK 12

[Harold David Seigel]

Hi,

Please review this fix for JDK-8207689.  Most of the VM options listed 
in the bug have already been deleted.  The only remaining thing to 
remove was a PerfCounter used with the UnsyncloadClass option.

JBS Bug:  https://bugs.openjdk.java.net/browse/JDK-8207689

The fix was tested by running Mach5 tiers 1 and 2 tests and builds on 
Linux-x64, Windows, and Mac OS X, running tiers 3-5 tests on Linux-x64, 
and by running JCK-12 Lang and VM tests on Linux-x64.

Thanks, Harold
