Bug #10699: m(*a, **b) doesn't recognize integer options.

----------------------------------------
It seems a method defined as m(*a, **b) doesn't recognize integer options.

```
% ./ruby -v -e '
def m(*a, **b)
  p [a, b]
end
m(1, 2 => 3)
m(1, :foo => 3)
'
ruby 2.3.0dev (2015-01-06 trunk 49159) [x86_64-linux]
[[1, {2=>3}], {}]
[[1], {:foo=>3}]
```

I think the result should be follows.

```
[[1], {2=>3}]
[[1], {:foo=>3}]
```

I found this problem by https://github.com/ruby/ruby/pull/808
