RR(S): 8022655: ClassDump ignored jarStream setting

Hi,

Review request for a small change in ClassDump:

http://cr.openjdk.java.net/~kevinw/8022655/webrev.00/

This was caused by moving some code from ClassDump's main method, 
breaking the intent that it has to maintain either an output director, 
OR a jarStream.  Setting of the directory could be done unconditionally 
when it was in main(), but not when in the run() method.

The tests test/compiler/ciReplay for compiler replay work (if you update 
sa.js with a suggested fix from 8011888).

Trying those tests now on Solaris, I found coreadm settings may mean 
they don't find the core: putting  a coreadm command in the test means 
we should find JTwork/scratch/core

Thanks
Kevin
