Use ActiveRecord::Base#update! instead of #update_attributes!
scope_chain should not be mutated for other reflections

Currently `scope_chain` uses same array for building different
`scope_chain` for different associations. During processing
these arrays are sometimes mutated and because of in-place
mutation the changed `scope_chain` impacts other reflections.

Fix is to dup the value before adding to the `scope_chain`.

Fixes #3882.
Minor Refactoring to `NumberHelper#number_to_human`

* Use destructive `map` and `sort_by` to save extra object creation.
* Create `INVERTED_DECIMAL_UNITS.invert` constant instead of repeatedly doing `DECIMAL_UNITS.invert`
Fix `singleton_class?`

Due to changes from http://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/39628 current `singleton_class?` implementation fails.
Changed based on reference from http://bugs.ruby-lang.org/issues/7609
Remove size alias for length validation

Removed ```The `size` helper is an alias for `length`.``` line. If you use this "nonexist" helper, you will get an error message like this: 

```
ArgumentError: Unknown validator: 'SizeValidator'
...
```

Maybe wanted to mean ```validates_size_of``` helper as an alias for ```validates_length_of``` helper.

Add 2 tests, 1 of which fails, to isolate the digest_caching behaviour causing #12521

If config.action_view.cache_template_loading = false, most likely in a development
configuration if config.cache_classes = false &
config.action_controller.perform_caching = true.

config.action_view.cache_template_loading defaults to the value of config.cache_classes
Ensure ActionView::Digest.cache is correctly cleaned up when
ActionView::Resolver.caching = false.
