Condenses the clauses that are common to both sides of the OR and put them outside, before the OR
This fix the current behavior where the number of conditions is exponential based on the number of times #or is used.

Note that the two relations must still have the same `includes` values
(which is the only time `references` actually does anything). It makes
sense for us to allow this, as `references` is called implicitly when
passing a hash to `where`.

Fix `COUNT(DISTINCT ...)` with `ORDER BY` and `LIMIT`

| | | | | | | | | | | |
Since #26972, `ORDER BY` is kept if `LIMIT` is presented for
performance. But in most SQL servers (e.g. PostgreSQL, SQL Server, etc),
`ORDER BY` expressions must appear in select list for `SELECT DISTINCT`.
We should not replace existing select list in that case.

Fix `counter_cache` double increment

| | | | | | | | | | | |
When an `after_create` callback did `update_attributes` on a record with
multiple `belongs_to` associations with counter caches, even numbered
associations would have their counters double-incremented. Fixes to
`ActiveModel::Dirty` in 020abad fixed this.
This adds regression tests for this bug fixed incidentally in the other
commit, which also removed the need for the workaround using
@_after_create_counter_called.

A common source of bugs and code bloat within Active Record has been the
need for us to maintain the list of bind values separately from the AST
they're associated with. This makes any sort of AST manipulation
incredibly difficult, as any time we want to potentially insert or
remove an AST node, we need to traverse the entire tree to find where
the associated bind parameters are.
With this change, the bind parameters now live on the AST directly.
Active Record does not need to know or care about them until the final
AST traversal for SQL construction. Rather than returning just the SQL,
the Arel collector will now return both the SQL and the bind parameters.
At this point the connection adapter will have all the values that it
had before.
A bit of this code is janky and something I'd like to refactor later. In
particular, I don't like how we're handling associations in the
predicate builder, the special casing of `StatementCache::Substitute` in
`QueryAttribute`, or generally how we're handling bind value replacement
in the statement cache when prepared statements are disabled.
This also mostly reverts #26378, as it moved all the code into a
location that I wanted to delete.

Sort enabled adapter extensions in schema dump

The list of enabled adapter extensions in the schema dump isn't
sorted by default, so it may happen that the sorting changes
over time. If you're using a VCS, a change to the sorting results
in a diff without any real change. Sorting the list should solve
this problem.

Make `type_map` to private because it is only used in the connection adapter

`type_map` is an internal API and it is only used in the connection
adapter. And also, some type map initializer methods requires passed
`type_map`, but those instances already has `type_map` in itself.
So we don't need explicit passing `type_map` to the initializers.

Match destroyed_by_association for has_one to has_many

When a has_many association is destroyed by `dependent: destroy`,
destroyed_by_association is set to the reflection, and this can be
checked in callbacks. This matches that behaviour for has_one
associations.

This reverts commit b6ad4052d18e4b29b8a092526c2beef013e2bf4f.
This is not something that the majority of Active Record should be
testing or care about. We should look at having fewer places rely on
these details, not make it easier to rely on them.

Make preload query to preparable

Currently preload query cannot be prepared statements even if
`prepared_statements: true` due to array handler in predicate builder
doesn't support making bind params. This makes preload query to
preparable by don't passing array value if possible.

Since 5c71000, it has lost to be able to unscope `default_scope` in STI
associations. This change will use `.empty_scope?` instead of
`.values.empty?` to regard as an empty scope if only have
`type_condition`.

Dates are able to be natively handled by the mysql2 gem. libmysql (and
the wire protocol) represent each portion of the date as an integer,
which is significantly faster to encode and decode. By passing the Ruby
date objects through directly, we can save a good bit of time and
memory.

This test was added at 74ed123 to ensure `respond_to?` delegate methods
to `Array` and `arel_table`. But array method delegation was removed at
9d79334 in favor of including `Enumerable`. And now `Relation` has
`insert`, `update`, and `delete` methods (63480d2, 8d31c9f, d5f9173).
So this delegation test is already outdated.
