Subject: [PATCH] [V8] Allow a script to be flagged as "native"

Native scripts do not appear in backtraces, or in the source and
line number when exceptions are thrown from within them.  This is
useful to be able to write code in JavaScript instead of C++ and
still have it appear sensibly to the user.
