beam_validator: Exit immediately on crashes
The beam_validator catches all exceptions and collect them. It makes more sense to don't catch 'error' and 'exit' exceptions, but to just print out the name of the current function and pass on the exception just as all other compilation passes do. Those kind of exceptions are the symptoms of the kind of severe but easily catched bugs that occur during development.
