This subtle bug showed up when compiling a library with 9.4.
See #22491. The bug is present in master, but it is hard to
trigger; the new regression test T22491 fails in 9.4.
The fix was easy: just add a missing varToCoreExpr in
etaBodyForJoinPoint.
The fix is definitely right though!
I also did some other minor refatoring:
* Moved the preInlineUnconditionally test in simplExprF1 to
before the call to joinPointBinding_maybe, to avoid fruitless
eta-expansion.
* Added a boolean from_lam flag to simplNonRecE, to avoid two
fruitless tests, and commented it a bit better.
These refactorings seem to save 0.1% on compile-time allocation in
perf/compiler; with a max saving of 1.4% in T9961

These jobs fail (and are allowed to fail) nearly every time.
Soon they won't even be able to run at all, as we won't currently have
runners that can run them.
Fixing the latter problem is tracked in #22409.
I went ahead and removed all settings and configurations.

This patch changes the representation of TyCon so that it has
a top-level product type, with a field that gives the details
(newtype, type family etc), #22458.
Not much change in allocation, but execution seems to be a bit
faster.
Includes a change to the haddock submodule to adjust for API changes.

This improves the error messages of the exhaustiveness checker when
checking statements which have been moved around with ApplicativeDo.
Before:
Test.hs:2:3: warning: [GHC-62161] [-Wincomplete-uni-patterns]
Pattern match(es) are non-exhaustive
In a pattern binding:
Patterns of type ‘Maybe ()’ not matched: Nothing
|
2 | let x = ()
| ^^^^^^^^^^
After:
Test.hs:4:3: warning: [GHC-62161] [-Wincomplete-uni-patterns]
Pattern match(es) are non-exhaustive
In a pattern binding:
Patterns of type ‘Maybe ()’ not matched: Nothing
|
4 | ~(Just res1) <- seq x (pure $ Nothing @())
