Currently if the --patch-module option is specified during CDS dump time, the jvm will exit with the following message:
Cannot use the following option when dumping the shared archive: --patch-module

and during runtime, the jvm will issue the following warning message:
The shared archive file cannot be used with --patch-module.

This bug fix is to allow the user to specify the --patch-module vm option when dumping and using CDS archive.

The fix will not archive any classes encountered in the --patch-module list.
The fix will also check for non-empty directory specified in the --patch-module option. If it detects an non-empty directory, it will abort dumping of the shared archive.
If the value of --patch-module specified during dump time doesn't match the one specified during run time, the vm will exit with an error message.
