Improvement in error reporting.

This fix prevents certain situations when an inappropriate form
is reported, in the default unhandled exception handler, as pertaining
to an error.

* eval.c (do_eval): Save and restore the last_form_evaled,
in an exception-unsafe way.  If we successfully evaluate a form or
subform, we can restore the previous one.
(expand): Save and restore last_form_expanded similarly. We don't
need the unwind block and counter.
