Allow order to be given expressions as hash keys
When `order` is given a hash, the keys are currently assumed to be
attribute names and are quoted as such in the query, which makes it
impossible to pass an expression instead:
Post.order("LENGTH(title)" => :asc).last
# SELECT `posts`.* FROM `posts` ORDER BY `posts`.`LENGTH(title)` DESC LIMIT 1
If the key is an `Arel::Nodes::SqlLiteral`, we now use it directly in
the query. This provides a way to build a relation with a complex order
clause that can still be reversed with `reverse_order` or `last`.
