--dry-run description enhancement

[Paul Benedict]

The current help of --dry-run is this:
"create VM but do not execute main method"

But I think it's pretty important to note that the class is also not even
loaded. Not even static initializers will execute. Does anyone think this
would would be a worthwhile tweak?

Suggestion:
"create VM but do not load mainclass or execute main method"

My allusion to "mainclass" comes from the --module option

Cheers,
Paul
