RFR 8234656: Improve granularity of verifier logging

[Harold Seigel]

Hi,

Please review this small change to improve the granularity of verifier 
logging.  This change provides brief output for log level info and 
detailed logging for log levels debug and trace. Additionally, it 
changes verifier test TraceClassRes.java to use the logging API command 
line options.

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8234656

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

Thanks, Harold
