Previously, derived instances of `Functor` (as well as the related classes
`Foldable`, `Traversable`, and `Generic1`) would determine which constraints to
infer by checking for fields that contain the last type variable. The problem
was that this last type variable was taken from `tyConTyVars`. For GADTs, the
type variables in each data constructor are _not_ the same type variables as
in `tyConTyVars`, leading to #22167.
This fixes the issue by instead checking for the last type variable using
`dataConUnivTyVars`. (This is very similar in spirit to the fix for #21185,
which also replaced an errant use of `tyConTyVars` with type variables from
each data constructor.)
Fixes #22167.

In the lexer, predicates have the following type:
{ ... } :: user -- predicate state
-> AlexInput -- input stream before the token
-> Int -- length of the token
-> AlexInput -- input stream after the token
-> Bool -- True <=> accept the token
This is documented in the Alex manual.
There is access to the input stream both before and after the token.
But when the time comes to construct the token, GHC passes only the
initial string buffer to the lexer action. This patch fixes it:
- type Action = PsSpan -> StringBuffer -> Int -> P (PsLocated Token)
+ type Action = PsSpan -> StringBuffer -> Int -> StringBuffer -> P (PsLocated Token)
Now lexer actions have access to the string buffer both before and after
the token, just like the predicates. It's just a matter of passing an
additional function parameter throughout the lexer.

Before this patch, the varsym lexing rules were defined as follows:
<0> {
@varsym / { precededByClosingToken `alexAndPred` followedByOpeningToken } { varsym_tight_infix }
@varsym / { followedByOpeningToken } { varsym_prefix }
@varsym / { precededByClosingToken } { varsym_suffix }
@varsym { varsym_loose_infix }
}
Unfortunately, this meant that the predicates 'precededByClosingToken' and
'followedByOpeningToken' were recomputed several times before we could figure
out the whitespace context.
With this patch, we check for whitespace context directly in the lexer
action:
<0> {
@varsym { with_op_ws varsym }
}
The checking for opening/closing tokens happens in 'with_op_ws' now,
which is part of the lexer action rather than the lexer predicate.

We now always merge .a archives when ar supports -L.
This change is necessary in order to bootstrap GHC using GHC 9.4
on Windows, as nested archives aren't supported.
Not doing so triggered bug #21990 when trying to use the Win32
package, with errors such as:
Not a x86_64 PE+ file.
Unknown COFF 4 type in getHeaderInfo.
ld.lld: error: undefined symbol: Win32zm2zi12zi0zi0_SystemziWin32ziConsoleziCtrlHandler_withConsoleCtrlHandler1_info
We have to be careful about which ar is meant: in stage 0, the check
should be done on the system ar (system-ar in system.config).

Due to an oversight, the initial specification and implementation of

This meant that expressions such as "x+ y" would produce a warning,
while "x:+ y" would not.
The specification was corrected in ghc-proposals pull request #404,
and this patch updates the implementation accordingly.

This change is approved by the Core Libraries commitee in
https://github.com/haskell/core-libraries-committee/issues/10
The first change makes the `Eq`, `Ord`, `Show`, and `Read` instances for
`Sum`, `Product`, and `Compose` match those for `:+:`, `:*:`, and `:.:`.
These have the proper flexible contexts that are exactly what the
instance needs:
For example, instead of
```haskell
instance (Eq1 f, Eq1 g, Eq a) => Eq (Compose f g a) where
(==) = eq1
```
we do
```haskell
deriving instance Eq (f (g a)) => Eq (Compose f g a)
```
But, that change alone is rather breaking, because until now `Eq (f a)`
and `Eq1 f` (and respectively the other classes and their `*1`
equivalents too) are *incomparable* constraints. This has always been an
annoyance of working with the `*1` classes, and now it would rear it's
head one last time as an pesky migration.
Instead, we give the `*1` classes superclasses, like so:
```haskell
(forall a. Eq a => Eq (f a)) => Eq1 f
```
along with some laws that canonicity is preserved, like:
```haskell
liftEq (==) = (==)
```
and likewise for `*2` classes:
```haskell
(forall a. Eq a => Eq1 (f a)) => Eq2 f
```
and laws:
```haskell
liftEq2 (==) = liftEq1
```
The `*1` classes also have default methods using the `*2` classes where
possible.
What this means, as explained in the docs, is that `*1` classes really
are generations of the regular classes, indicating that the methods can
be split into a canonical lifting combined with a canonical inner, with
the super class "witnessing" the laws[1] in a fashion.
Circling back to the pragmatics of migrating, note that the superclass
means evidence for the old `Sum`, `Product`, and `Compose` instances is
(more than) sufficient, so breakage is less likely --- as long no
instances are "missing", existing polymorphic code will continue to
work.
Breakage can occur when a datatype implements the `*1` class but not the
corresponding regular class, but this is almost certainly an oversight.
For example, containers made that mistake for `Tree` and `Ord`, which I
fixed in https://github.com/haskell/containers/pull/761, but fixing the
issue by adding `Ord1` was extremely *un*controversial.
`Generically1` was also missing `Eq`, `Ord`, `Read,` and `Show`
instances. It is unlikely this would have been caught without
implementing this change.
-----
[1]: In fact, someday, when the laws are part of the language and not
only documentation, we might be able to drop the superclass field of the
dictionary by using the laws to recover the superclass in an
instance-agnostic manner, e.g. with a *non*-overloaded function with
type:
```haskell
DictEq1 f -> DictEq a -> DictEq (f a)
```
But I don't wish to get into optomizations now, just demonstrate the
close relationship between the law and the superclass.

The hack to add extra dependencies needed by DeriveLift extension missed
the cases for profiles and dynamic ways. For the profiled way this leads
to errors like:
```
GHC error in desugarer lookup in Data.IntSet.Internal:
Failed to load interface for ‘Language.Haskell.TH.Lib.Internal’
Perhaps you haven't installed the profiling libraries for package ‘template-haskell’?
Use -v (or `:set -v` in ghci) to see a list of the files searched for.
ghc: panic! (the 'impossible' happened)
GHC version 9.5.20220916:
initDs
```
Therefore the fix is to add these extra edges in.
Fixes #22197

The function GHC.Stg.InferTags.Rewrite.isTagged can be given
the Id of a join point, which might be representation polymorphic.
This would cause the call to isUnliftedType to crash. It's better
to use typeLevity_maybe instead.
