306b687520 Refs #11964 -- Removed SimpleCol in favor of Query(alias_cols). 
This prevent having to pass simple_col through multiple function calls
by defining whether or not references should be resolved with aliases
at the Query level.

11e327a3ff Fixed #30988 -- Deprecated the InvalidQuery exception. 
It was barely documented without pointers at its defining location and
was abused to prevent misuse of the QuerySet field deferring feature.

d0c86a1df4 Refs #29808 -- Optimized MigrationExecutor.detect_soft_applied(). 
Use set() for iterables used only for containment checks. Simplify
column checks O(n) instead of O(2n).

Thanks Simon Charette for an idea.

7286eaf681 Refs #13312 -- Simplified handling of nulls ordering on MySQL. 
MySQL & MariaDB support the standard IS NULL and IS NOT NULL so
the same workaround used for NULLS FIRST and NULLS LAST that is
used for SQLite < 3.30.0 can be used.

Thanks Simon Charette for the discussion.

a699595fce Refs #13312 -- Removed unnecessary IF wrapping in nulls_last handling on MySQL. 
ISNULL function already returns 0 and 1 on MySQL.

a9bd01d363 Refs #30095 -- Simplified Field._check_choices() a bit. 
Using an internal is_value() hook to check whether Field.choices
is iterable is misleading.

dbcd7b064e Fixed #30902 -- Added __str__() for model choice enums. 
Allows expected behavior when cast to str, also matching behaviour of
created instances with those fetched from the DB.

7acef095d7 Fixed #23576 -- Implemented multi-alias fast-path deletion in MySQL backend. 
This required moving the entirety of DELETE SQL generation to the
compiler where it should have been in the first place and implementing
a specialized compiler on MySQL/MariaDB.

The MySQL compiler relies on the "DELETE table FROM table JOIN" syntax
for queries spanning over multiple tables.

681f7e2b13 Fixed #20577 -- Deferred filtering of prefetched related querysets. 
Added internal interface to QuerySet that allows to defer next filter
call till .query is accessed. Used it to optimize prefetch_related().

Thanks Simon Charette for the review.

70d8146986 Adjusted QuerySet._filter_or_exclude() call to use negated=False, rather than None. 
None was a remnant from the times _filter_or_exclude accepted
qtype/mapper as the first arg.
