Hi Team,<br>
<br>
First review request. Please let me know if I've forgotten something
or have gone completely off the rails.<br>
<br>
The main point of this bug is to remove deprecated -XX options which
are alias for other options.<br>
<br>
The only complicated part is that one case,
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<i>CMSParPromoteBlocksToClaim</i> was not a true alias for <i>OldPLABSize</i>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
but a parallel option with different defaults that were synchronized
in ergo processing. This fix removes the <i>CMSParPromoteBlocksToClaim
</i>variable but preserves using different defaults in the CMS case.<br>
<br>
Also in this fix I added warning messages to several remaining
undocumented command line options aliases. This should ease removal
of these options in the future<br>

G1MarkStackSize ==> MarkStackSize

ParallelMarkingThreads => ConcGCThreads (ConcGCThreads came in jdk6)

Thanks,<br>

Saw 1-2 intermittent failures that went away on retesting -
hangs and timeouts.<br>

no differences<br>
