The bind values can come from four places. `having`, `where`, `joins`, and `from` when selecting from a subquery that contains binds. These need to be kept in a specific order, since the clauses will always appear in that order. Up until recently, they were not. Additionally, `joins` actually did keep its bind values in a separate location (presumably because it's the only case that people noticed was broken). However, this meant that anything accessing just `bind_values` was broken (which most places were). This is no longer possible, there is only a single way to access the bind values, and it includes joins in the proper location. The setter was removed yesterday, so breaking `+=` cases is not possible. I'm still not happy that `joins` is putting it's bind values on the Arel AST, and I'm planning on refactoring it further, but this removes a ton of bug cases.

Overriding these methods may cause unexpected results since "table_name=" does more then just setting the "@table_name". ref: https://github.com/rails/rails/pull/18622#issuecomment-70874358

Contrary to my previous commit message, it wasn't overkill, and led to much cleaner code. [Sean Griffin & anthonynavarre]

The last place that was assigning it was when `from` is called with a relation to use as a subquery. The implementation was actually completely broken, and would break if you called `from` more than once, or if you called it on a relation, which also had its own join clause, as the bind values would get completely scrambled. The simplest solution was to just move it into its own array, since creating a `FromClause` class for this would be overkill.

This removes the need to duplicate much of the logic in `WhereClause` and `PredicateBuilder`, simplifies the code, removes the need for the connection adapter to be continuously passed around, and removes one place that cares about the internal representation of `bind_values` Part of the larger refactoring to change how binds are represented internally [Sean Griffin & anthonynavarre]

The Relation will ultimately end up holding a reference to the arel table object, and its associated type caster. If this is a `TypeCaster::Connection`, that means it'll hold a reference to the connection adapter, which cannot be marshalled. We can work around this by just holding onto the class object instead. It's ugly, but I'm hoping to remove the need for the connection adapter type caster in the future anyway. [Sean Griffin & anthonynavarre]

This fixed an issue where `having` can only be called after the last call to `where`, because it messes with the same `bind_values` array. With this change, the two can be called as many times as needed, in any order, and the final query will be correct. However, once something assigns `bind_values`, that stops. This is because we have to move all of the bind values from the having clause over to the where clause since we can't differentiate the two, and assignment was likely in the form of: `relation.bind_values += other.bind_values` This will go away once we remove all places that are assigning `bind_values`, which is next on the list. While this fixes a bug that was present in at least 4.2 (more likely present going back as far as 3.0, becoming more likely in 4.1 and later as we switched to prepared statements in more cases), I don't think this can be easily backported. The internal changes to `Relation` are non-trivial, anything that involves modifying the `bind_values` array would need to change, and I'm not confident that we have sufficient test coverage of all of those locations (when `having` was called with a hash that could generate bind values).

When we made sure that the counter gets updated in memory, we only did it on the has many side. The has many side only does the update if the belongs to cannot. The belongs to side was updated to update the counter cache (if it is able). This means that we need to check if the belongs_to is able to update in memory on the has_many side. We also found an inconsistency where the reflection names were used to grab the association which should update the counter cache. Since reflection names are now strings, this means it was using a different instance than the one which would have the inverse instance set. Fixes #18689 [Sean Griffin & anthonynavarre]

There are many ways that things end up getting passed to `concat`. Not all of those entry points called `flatten` on their input. It seems that just about every method that is meant to take a single record, or that splats its input, is meant to also take an array. `concat` is the earliest point that is common to all of the methods which add records to the association. Partially fixes #18689

The code assumes that non-single-value methods mean multi value methods. That is not the case. We need to change the accessor name, and only assign an array for multi value methods

This object being a black box, it knows the details of how to merge itself with another where clause. This removes all references to where values or bind values in `Relation::Merger`

The way that bind values are currently stored on Relation is a mess. They can come from `having`, `where`, or `join`. I'm almost certain that `having` is actually broken, and calling `where` followed by `having` followed by `where` will completely scramble the binds. Joins don't actually add the bind parameters to the relation itself, but instead add it onto an accessor on the arel AST which is undocumented, and unused in Arel itself. This means that the bind values must always be accessed as `relation.arel.bind_values + relation.bind_values`. Anything that doesn't is likely broken (and tons of bugs have come up for exactly that reason) The result is that everything dealing with `Relation` instances has to know far too much about the internals. The binds are split, combined, and re-stored in non-obvious ways that makes it difficult to change anything about the internal representation of `bind_values`, and is extremely prone to bugs. So the goal is to move a lot of logic off of `Relation`, and into separate objects. This is not the same as what is currently done with `JoinDependency`, as `Relation` knows far too much about its internals, and vice versa. Instead these objects need to be black boxes that can have their implementations swapped easily. The end result will be two classes, `WhereClause` and `JoinClause` (`having` will just re-use `WhereClause`), and there will be a single method to access the bind values of a `Relation` which will be implemented as ``` join_clause.binds + where_clause.binds + having_clause.binds ``` This is the first step towards that refactoring, with the internal representation of where changed, and an intermediate representation of `where_values` and `bind_values` to let the refactoring take small steps. These will be removed shortly.

The structure of `values[:where]` is going to change, with an intermediate definition of `where_values` to aid the refactoring. Accessing `values[:where]` directly messes with that, signficantly. The array wrapping is no longer necessary, since `where_values` will always return an array.
