RFR(T): 8234544: ObjectSynchronizer::FastHashCode() cleanups from Async Monitor Deflation project

[Daniel D. Daugherty]

Greetings,

I have another round of baseline cleanup changes from the Async Monitor
Deflation project (8153224). Only comments have been changed with this
one so I'm considering this changeset to be trivial.

Please see the bug for details about the changes in this webrev:

JDK-8234544 ObjectSynchronizer::FastHashCode() cleanups from Async
                 Monitor Deflation project
     https://bugs.openjdk.java.net/browse/JDK-8234544

Here's the webrev URL:

http://cr.openjdk.java.net/~dcubed/8234544-webrev/0-for-jdk14/

These changes have been tested with a Mach5 Tier[1-3] just because
I'm paranoid. :-)

Thanks, in advance, for any comments, questions or suggestions.

Dan
