3f7b327562 Fixed #31235 -- Made assertQuerysetEqual() compare querysets directly. 
This also replaces assertQuerysetEqual() to
assertSequenceEqual()/assertCountEqual() where appropriate.

8593e162c9 Fixed #32143 -- Used EXISTS to exclude multi-valued relationships. 
As mentioned in the pre-existing split_exclude() docstring EXISTS is
easier to optimize for query planers and circumvents the IN (NULL)
handling issue.

bbf141bcdc Refs #27149 -- Fixed sql.Query identity. 
By making Query subclass BaseExpression in
3543129822 the former defined it's
identity based off _construct_args which is not appropriate.

Fixed some queries tests when primary key values are large. 
On CockroachDB, primary key values stored in these fields are larger
than they accept. Fixes:
queries.test_bulk_update.BulkUpdateNoteTests.test_multiple_fields,
queries.test_bulk_update.BulkUpdateNoteTests.test_inherited_fields, and
queries.tests.RelatedLookupTypeTests.test_values_queryset_lookup.

The code from the original fix (922aba3def)
was removed in 419de7b00d.

f4ac167119 Fixed #27719 -- Added QuerySet.alias() to allow creating reusable aliases. 
QuerySet.alias() allows creating reusable aliases for expressions that
don't need to be selected but are used for filtering, ordering, or as
a part of complex expressions.

Thanks Simon Charette for reviews.

This allowed the Note model to be used in setUpTestData() which requires
assigned model instances to be copy.deepcopy()'able.

98ea4f0f46 Refs #7098 -- Deprecated passing raw column aliases to order_by(). 
Now that order_by() has expression support passing RawSQL() can achieve
the same result.

This was also already supported through QuerySet.extra(order_by) for
years but this API is more or less deprecated at this point.

306b687520 Refs #11964 -- Removed SimpleCol in favor of Query(alias_cols).

at the Query level.

It was barely documented without pointers at its defining location and
was abused to prevent misuse of the QuerySet field deferring feature.

13a8884a08 Fixed #30739 -- Fixed exclusion of multi-valued lookup against outer rhs. 
OuterRef right hand sides have to be nested, just like F rhs have to,
during the subquery pushdown split_exclude performs to ensure they are
resolved against the outer query aliases.
