This came up while trying to debug some stuff going on in the snapshot, makes debugging a lot easier. IDK if we want to do something other than use abort() here.

Sorry for missing the ping: just FYI SetIsolateErrorHandlers() can install error handlers that print uncaught exceptions and it's used by the ordinary Node.js instances - I don't quite remember why it wasn't used by mksnapshot, though. Also there are some routines in node_errors.cc that can be reused to print these errors.
