Translator call fix

So I went ahead and addressed the issue regarding qualifiers on calls to operations derived from enhanced facilities. That part was easy. But I also had to tweak translation qualifying logic in general -- which risks affecting many things. I've tested this fix on alt_rev_stack, copystack, and revstack. I've also tested it on variants of these that use only one enhancement (it actually matters in terms of Java output). If this causes a ton of problems that weren't problems before, we can always revert.
