Alright, done!  I added to the builtins-elementwise.c and here.  I did NOT pull in math-builtins.c.  It has a lot more configurations that we dont compile yet, and has a ton of builtins we don't do anything with yet.  We should probably do so eventually, but I am pretty convinced we're not there yet.
