Improve the error diagnostics.
I was looking at a problem where a test seemingly hangs forever. I tracked it
down to a problem in CPS VM,
but what made this difficult for me is that a RuntimeException happening in
some unexpected part of CPS VM went unreported.
If this error happened in the field, I would have never been able to figure
this out. So I'm adding a diagnostics here to make sure
we can catch this class of problems.
Just for the record, the particular problem in CPS VM is a NullPointerException
in the following place:
