This is a semver-major change that resolves DEP0018.
All users that have set an unhandledRejection hook or set a non-default
value for the --unhandled-rejections flag will see no change in behavior
after this change.

This PR defines two new modes for the --unhandled-rejections flag.
The first mode is called "throw". The "throw" mode first emits
unhandledRejection. If this hook is not set, the "throw" mode will
raise the unhandled rejection as an uncaught exception.
The second mode is called "warn-with-error-code". The
"warn-with-error-code" mode first emits unhandledRejection. If this
hook is not set, the "warn-with-error-code" mode will trigger a
warning and set the process's exit code to 1.
The PR doesn't change the default behavior for unhandled rejections.
That will come in a separate PR.
