[This updated webrev is being sent to wider audience, and has been
merged with Gerard's option constraints check-in. Also factored
out -XX:+AggressiveHeap processing into it's own chapter. I mean
function :-)]<br>

<br>
This webrev adds support for handling "<i>deprecated</i>" -XX
options (options that still <b>do</b> something but are planned
for removal) and "<i>alias</i>" options (alternate names for other
-XX options) by simply adding entries to the deprecated_jvm_flags
and/or aliased_jvm_flags tables. This follows the example of the
existing obsolete_jvm_flags table.<br>
<br>
This replaces a lot of ad-hoc and occasionally wrong code in
arguments.cpp as well as supporting automatically disabling
options after a certain version.<br>
<br>
Tests:<br>
Deprecated and alias options can be tested by adding entries to
tables in new tests:<br>
VMAliasOptions.java<br>
VMDeprecatedOptions.java<br>
<br>
The new tests subsume these existing tests:<br>
test/gc/startup_warnings/TestDefaultMaxRAMFraction.java<br>
test/gc/startup_warnings/TestNoParNew.java <br>
<br>
Tests run:<br>
jprt<br>
jtreg (investigating errors in resource mgmt tests running on
SE embedded that seems unrelated to these changes.)<br>
<br>
Thanks,<br>
