Hi all,
Please review this.
This changeset moves redefine classes tracing to UL.
Bug: https://bugs.openjdk.java.net/browse/JDK-8153535
Webrev: http://cr.openjdk.java.net/~rehn/8153535/rev_01/webrev/
Passes testsuits
jdk/test/:jdk_jdi,hotspot/test/:hotspot_all,nsk.jvmti.testlist,nsk.jdi.testlist
with:
-Xlog:redefine+class*=trace
(a few test won't run with extra options)
-XX:TraceRedefineClasses=xyz turns on (aliased with)
"-Xlog:redefine+class*=info" and emits a warning.
(xyz is ignored)
Thanks!

Example of useage:
-Xlog:redefine+class+constantpool*=debug
-Xlog:redefine+class+load=info
-Xlog:redefine+class*=debug,redefine+class+iklass*=trace
