[ver. General] Convert a while-loop to a tail-recursive func

// Input you a code using a loop

def [
+ type param
] (
+ param
): = {
+ local var
while(){
}

}

// Output - Auto-generated tailrec

// Scala(tailrec)

_{{func_name}}( new{{to_first_upper(local_var.name)}} , )
} else {{ret_val}}

// Input confirmation
