Make "N for M" into the form "given N, expected M".
As I worked, I noticed that the `argnum_error()` function had a part to include the method name in the message.
I think this part is no longer needed by https://github.com/mruby/mruby/pull/5394.
- Before this patch
```console
% bin/mruby -e '[1, 2, 3].each 0'
trace (most recent call last):
[1] -e:1
-e:1:in each: 'each': wrong number of arguments (1 for 0) (ArgumentError)
```
- After this patch
```console
% bin/mruby -e '[1, 2, 3].each 0'
trace (most recent call last):
[1] -e:1
-e:1:in each: wrong number of arguments (given 1, expected 0) (ArgumentError)
```

The Ruby version of `Array#rotate!` generated a rotated array and
replaced the receiver, but the C version rotates the receiver array
in-place. So the performance is improved a lot both in speed and memory
consumption. Look for the comments in `array.c` for the in-place rotating
algorithm, if you are interested.
I get an error because the current mruby does not have a `Kernel#warn` method.
But the warning itself is useful and I'll just comment it out in case it's implemented in the future.
Before this patch:
$ bin/mruby -e '[1].permutation(-1){|v| p v}' #=> [1]
After this patch (same as Ruby):
$ bin/mruby -e '[1].permutation(-1){|v| p v}' #=> no output
Example benchmark:
$ time build/bench/bin/mruby -e "Array.new(2_000_000){ |i| i }.index{ |i| i == 1_999_999 }"
