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.
