erl_lint: Add a deprecated warning for literal tuple funs
The run-time warning for use of tuple funs will not catch the use of literal tuple funs, such as: if {erlang,'+'}(3,X) =:= 0 -> true; true -> false end. Therefore, add a compile-time warning to give users some warning before they stop working in R16.
