----------------------------------------
Attempting to call `Marshal.dump` on an `ActiveSupport::CoreExtensions::Numeric::Time` (e.g., `1.day`) triggers a ```NoMethodError: undefined method `marshal_dump' for 86400:Fixnum``` exception in both Ruby 2.3.0 and 2.3.1 on OS X (10.11.4) and in Travis CI with ActiveSupport 4.1.15. This works correctly in previous versions, including 2.2.5.

To reproduce:

```
% rbenv install 2.3.1
...
% rbenv global 2.3.1
% gem install activesupport -v 4.1.15
...
% ruby --version    
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
% irb
irb(main):001:0> require 'active_support/core_ext/numeric/time'
=> true
irb(main):002:0> Marshal.dump(1.day)
NoMethodError: undefined method `marshal_dump' for 86400:Fixnum
	from ~/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activesupport-4.1.15/lib/active_support/duration.rb:115:in `method_missing'
	from (irb):2:in `dump'
	from (irb):2
	from ~/.rbenv/versions/2.3.1/bin/irb:11:in `<main>'
```

In 2.2.5:

```
% rbenv install 2.2.5
...
% rbenv global 2.2.5
% gem install activesupport -v 4.1.15
...
% ruby --version
ruby 2.2.5p319 (2016-04-26 revision 54774) [x86_64-darwin15]
% irb                                
irb(main):001:0> require 'active_support/core_ext/numeric/time'
=> true
irb(main):002:0> Marshal.dump(1.day)
=> "\x04\bo:\x1CActiveSupport::Duration\a:\v@valuei\x03\x80Q\x01:\v@parts[\x06[\a:\tdaysi\x06"
```
