Add support for aborts. (#2176)

Browse Source 
Aborts are similar to exceptions except they are not caught by catch
and finally blocks. Callbacks should honor aborts as well and return
them without processing them. Aborts are never thrown by JavaScript
code.

In the future certain events such as out-of-memory condition may
also throw aborts.
