RFR 8221685: -XX:BytecodeVerificationRemote and -XX:BytecodeVerificationLocal should be diagnostic options

[Harold Seigel]

Hi,

Please review this change to make the hotspot BytecodeVerification* 
options be diagnostic.  Use of either of these options without 
-XX:+UnlockDiagnosticVMOptions will now result in the following message:

     > java -XX:+BytecodeVerificationLocal -version
     Error: VM option 'BytecodeVerificationLocal' is diagnostic and must 
be enabled via -XX:+UnlockDiagnosticVMOptions.

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8221685

The fix was regression tested by running Mach5 tiers 1 and 2 tests and 
builds on Linux-x64, Windows, and Mac OS X, Mach5 tiers 3 -5 on 
Linux-x64, and by running JCK-13 Lang and VM tests on Linux-x64. 
Additionally, the java command was run to ensure that 
-XX:+UnlockDiagnosticVMOptions is needed when specifying the 
BytecodeVerification* options.

Thanks, Harold
