This -fno-cse change is to avoid these performance tests depending on
flukey CSE stuff.  Each contains several independent tests, and we don't
want them to interact.

See #23925.

By killing CSE we expect a 400% increase in T15426, and 100% in T18964.

Metric Increase:

that they expect the function to be specialised. However, previously
this instruction could be preempted by the specialised-argument limit
(sc_max_args). Fix this.

Issue #23922 showed that GHC was bogusly eta-reducing a join point.
We should never eta-reduce (\x -> j x) to j, if j is a join point.

It is extremly difficult to trigger this bug.  It took me 45 mins of
trying to make a small tests case, here immortalised as T23922a.

As the Lint error in #23952 showed, the function adjustJoinPointType
was failing to adjust the FunTyFlag when adjusting the type.

I don't think this caused the seg-fault reported in the ticket,
but it is definitely.  This patch fixes it.

This commit adjusts the validity checking of data family
instances to improve the reporting of unused type variables.

See Note [Out of scope tvs in data family instances] in GHC.Tc.Validity.

The problem was that, in a situation such as

  data family D :: Type
  data instance forall (d :: Type). D = MkD

the RHS passed to 'checkFamPatBinders' would be the TyCon app

  R:D d

which mentions the type variable 'd' quantified in the user-written
forall. Thus, when computing the set of unused type variables in
the RHS of the data family instance, we would find that 'd' is used,
and report a strange error message that would say that 'd' is not
bound on the LHS.

To fix this, we special-case the data-family instance case,
manually extracting all the type variables that appear in the
arguments of all the data constructores of the data family instance.

This commit changes how we perform some validity checking for
coercion axioms to mirror how we handle default declarations for
associated type families. This allows us to keep track of whether
type variables in type and data family instances were user-written
or not, in order to only report the user-written ones in
"unused type variable" error messages.

Consider for example:

  {-# LANGUAGE PolyKinds #-}
  type family F
  type instance forall a. F = ()

In this case, we get two quantified type variables,
(k :: Type) and (a :: k); the second being user-written, but the first
is introduced by the typechecker. We should only report 'a' as being
unused, as the user has no idea what 'k' is.

errors when the actually probably is usually completely unrelated except

(I can always pass `-VVV` to Hadrian locally, but these errors are

Clean up the m4 to handle the auto case always and be more consistent.
Also simplify the CPP --- we should always have both headers if we are
using libnuma.

"side effects" (AC_DEFINE, and AC_SUBST) are removed from the macros to
better separate searching from actions taken based on search results.
This might seem overkill now, but will make shuffling logic between
configure scripts easier later.

The macro comments are converted from `dnl` to `#` following the
recomendation in
https://www.gnu.org/software/autoconf/manual/autoconf-2.71/html_node/Macro-Definitions.html

The function 'stgArgType' returns the type in STG. But this violates
the abstraction: in STG we're supposed to operate on PrimReps.

This introduces
stgArgRep ty = typePrimRep (stgArgType ty)
stgArgRep1 ty = typePrimRep1 (stgArgType ty)
stgArgRep_maybe ty = typePrimRep_maybe (stgArgType ty)

stgArgType is still directly used for unboxed tuples (should be fixable), FFI
and in ticky.

  codes:outdated - list outdated diagnostic codes

This allows users to easily query GHC for used and outdated
diagnostic codes, e.g.

  hadrian/build -j --flavour=<..> codes

will list all used diagnostic codes in the command line by running
the lint-codes utility in the "list codes" mode of operation.

The diagnostic code consistency and coverage test is still run as usual,

This MR is pure refactoring (#23916):
* Combine `HsLam` and `HsLamCase`
* Combine `HsCmdLam` and `HsCmdLamCase`

This just arranges to treat uniformly
   \x -> e
   \case pi -> ei
   \cases pis -> ie

In the exising code base the first is treated differently
to the latter two.

No change in behaviour.

More specifics:

* Combine `HsLam` and `HsLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsExpr`) into one data construtor covering
  * Lambda
  * `\case`
  * `\cases`

* The new `HsLam` has an argument of type `HsLamVariant` to distinguish the three cases.

* Similarly, combine `HsCmdLam` and `HsCmdLamCase` (constructors of `Language.Haskell.Syntax.Expr.HsCmd` ) into one.

* Similarly, combine `mkHsLamPV` and `mkHsLamCasePV` (methods of class `DisambECP`) into one. (Thank you Alan Zimmerman.)

* Similarly, combine `LambdaExpr` and `LamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsMatchContext`) into one: `LamAlt` with a `HsLamVariant` argument.

* Similarly, combine `KappaExpr` and `ArrowLamCaseAlt` (constructors of `Language.Haskell.Syntax.Expr.HsArrowMatchContext`) into one: `ArrowLamAlt` with a `HsLamVariant` argument.

* Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one.

* Similarly, combine `PsErrLambdaInPat` and `PsErrLambdaCaseInPat` (constructors of `GHC.Parser.Errors.Ppr.PsError`) into one.

* In the same `PsError` data type, combine `PsErrLambdaCmdInFunAppCmd` and `PsErrLambdaCaseCmdInFunAppCmd` into one.

* In the same `PsError` data tpye, combine `PsErrLambdaInFunAppExpr` and `PsErrLambdaCaseInFunAppExpr` into one.

p* Smilarly combine `ExpectedFunTyLam` and `ExpectedFunTyLamCase` (constructors of `GHC.Tc.Types.Origin.ExpectedFunTyOrigin`) into one.

We currently use the Monoid class as a constraint on Exact Print
Annotation functions, so we can use mempty. But this leads to
requiring Semigroup instances too, which do not always make sense.

Instead, introduce a class NoAnn, with a function noAnn analogous to
mempty.

Closes #20372

This commit introduces a language extension, `OrPatterns`, as described in proposal 0522.

It extends the syntax by the production
`pat -> (one of pat1, ..., patk)`.
The or-pattern `pat` succeeds iff one of the patterns `pat1`, ..., `patk` succeed, in this order.

Currently, or-patterns cannot bind variables. They are still of great use as they discourage the use of wildcard patterns in favour of writing out all "default" cases explicitly:

```
isIrrefutableHsPat pat = case pat of
  ...
  (one of WildPat{}, VarPat{}, LazyPat{})
      = True
  (one of PArrPat{}, ConPatIn{}, LitPat{}, NPat{}, NPlusKPat{}, ListPat{})
      = False
```

This makes code safer where data types are extended now and then - just like GHC's `Pat` in the example when adding the new `OrPat` constructor. This would be catched by `-fwarn-incomplete-patterns`, but not when a wildcard pattern was used.
