Mariusz Felisiak 93a42d43a6 [4.0.x] Fixed #33159 -- Reverted "Fixed #32970 -- Changed WhereNode.clone() to create a shallow copy of children."
This reverts commit e441847eca.

A shallow copy is not enough because querysets can be reused and
evaluated in nested nodes, which shouldn't mutate JOIN aliases.

Thanks Michal Čihař for the report.

Keryn Knight 5353e7c250 Refs #27624 -- Optimized Query.clone() for non-combined queries.
This avoids constructing a generator expression and a new tuple if the
Query has no combined queries.

Adam Johnson 2931d847c2 Optimized Query.clone() a bit.
This removes unnecessary "if ... is None" branches, which are already
shallow-copied in the __dict__.copy() call.

Keryn Knight bf5abf1bdc Fixed #33025 -- Avoided accessing the database connections in Query.build_lookup() when not necessary.
Of the built-in backends, only Oracle treats empty strings and nulls as
equal, so avoid testing the default connection backend for
interprets_empty_strings_as_nulls if it can be established from the
lookup that it wouldn't affect the lookup instance returned. This
improves performance a small amount for most lookups being built,
because accessing the connections requires touching the thread critical
`Local` which is an expensive operation.

Keryn Knight 921e4ccb77
Fixed #33003 -- Removed **kwargs from QuerySet._chain().
The functionality of updating the __dict__ was only present to allow
for pickling a Prefetch object, which is a comparably rare operation.
Forcing the __getstate__() implementation to handle it allows the
chaining operation to be slightly faster, which is much more common.

Nick Touran 5d4f21b16f Fixed #32983 -- Added system check for redundant related_name on symmetrical M2M fields.
Since ManyToManyFields defined with `symmetrical=True` do not add a
related field to the target model, including a `related_name` argument
will never do what the coder likely expects. This makes including
a related_name with a symmetrical model raise a system check warning.

Keryn Knight 9662193aea Refs #32946 -- Changed internal usage of dynamic Q() objects construction to use non-kwargs initialization.

objects to create a single Q() object instead of many and then
combining them, where possible.

Simon Charette 9f3cce172f Refs #26430 -- Re-introduced empty aggregation optimization.
The introduction of the Expression.empty_aggregate_value interface
allows the compilation stage to enable the EmptyResultSet optimization
if all the aggregates expressions implement it.

This also removes unnecessary RegrCount/Count.convert_value() methods.
Disabling the empty result set aggregation optimization when it wasn't
appropriate prevented None returned for a Count aggregation value.

Thanks Nick Pope for the review.
