cjihrig 57003520f8 src: attach error to stack on displayErrors

The vm module's displayErrors option attaches error arrow
messages as a hidden property. Later, core JavaScript code
can optionally decorate the error stack with the arrow message.
However, when user code catches an error, it has no way to
access the arrow message. This commit changes the behavior of
displayErrors to mean "decorate the error stack if an error
occurs."
