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.

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.

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

Removed unnecessary reuse_with_filtered_relation argument from Query methods.
...
In Query.join() the argument reuse_with_filtered_relation was used to
determine whether to use == or .equals(). As this area of code is
related to aliases, we only expect an instance of Join or BaseTable to
be provided - the only two classes that provide .equals().
In both cases, the implementations of __eq__() and equals() are based
on use of the "identity" property. __eq__() performs an isinstance()
check first, returning NotImplemented if required. BaseTable.equals()
then does a straightforward equality check on "identity". Join.equals()
is a little bit different as it skips checking the last element of the
"identity" property: filtered_relation. This was only included
previously when the with_filtered_relation argument was True, impossible
since bbf141bcdc

Fixed #32632 , Fixed #32657 -- Removed flawed support for Subquery deconstruction.
...
Subquery deconstruction support required implementing complex and
expensive equality rules for sql.Query objects for little benefit as
the latter cannot themselves be made deconstructible to their reference
to model classes.
Making Expression @deconstructible and not BaseExpression allows
interested parties to conform to the "expression" API even if they are
not deconstructible as it's only a requirement for expressions allowed
in Model fields and meta options (e.g. constraints, indexes).
Thanks Phillip Cutter for the report.
This also fixes a performance regression in bbf141bcdc
