2015-07-11Teach Dialyzer arity of funs with literal arityLuca Favatella
Re-insert logic for `erlang:make_fun/3` in `erl_bif_types`. It had been removed in bd941f5 while type spec-ing `erlang.erl`. Type spec in `erlang.erl` cannot express arity of returned fun based on value of argument hence re-introducing logic in `erl_bif_types`. Re-definition of logic in `erl_bif_types` follows approach in 9d870a0.
