Enormous amount of output when missing SMTLib translation running `krun --prove`

As demonstrated there, krun --prove generates an enormous amount of (highly redundant) output sometimes when Z3 translations are not present.

Is there a way we can be smarter about what is output to the user? Perhaps only output "missing SMTLib translation" once per missing symbol?

I think the simplest thing to do is just emit the error message and not the stack trace. Is anyone really gaining any information from those stack traces?

So you mean what would show up is still:

java.lang.UnsupportedOperationException: missing SMTLib translation for .WordStack

But none of the lines like:

        at org.kframework.backend.java.symbolic.KILtoSMTLib.translate(KILtoSMTLib.java:241)

This sounds like a good fix to me. I think there would still be some redundancy in the output though, as it seems that the same missing translation gets reported multiple times.

I mean, sure, but the main problem is that it's massively verbose, and this would take it from hundreds of lines down to maybe 10 at most.
