We have an exitLld() function that can be used to exit lld without
running the normal atexit() handlers, destructors, etc. In some cases,
there is still some code we need to run when lld exits. This patch
adds an addLldExitHandler() function which allows the registration
of handlers which will be run by exitLld(). It also moves exitLld()
into its own file.
