Here we introduce a new flag to the testsuite driver,
--unexpected-output-dir=<dir>, which allows the user to ask
the driver to preserve unexpected output from tests. The intent is for
this to be used in CI to allow users to more easily fix unexpected
platform-dependent output.

This is a compile_and_run variant which also captures the GHC's
stderr. The warn_and_run name is best I can come up with,
as compile_and_run is taken.
This is useful specifically for testing warnings. We want to test that
when warning triggers, and it's not a false positive, i.e. that the
runtime behaviour is indeed "incorrect".
As an example a single test is altered to use warn_and_run

ld.gold appears to produce invalid static constructor tables on i386.
While ideally we would add an autoconf check to check for this

summarily reject such linkers on i386.

require until #23195 has been completed.
Subsequently this has broken nighty jobs such as the rocky8 job which in

Previously our recompilation check was quite inconsistent in its
coverage of non-optimisation code generation flags. Specifically, we
failed to account for most flags that would affect the behavior of
generated code in ways that might affect the result of a program's
execution (e.g. `-feager-blackholing`, `-fstrict-dicts`)

similar.

Commit 3f374399 inadvertently broke the deprecation/warning mechanism
for record fields due to its introduction of record field namespaces.
This patch ensures that, when a top-level deprecation is applied to
an identifier, it applies to all the record fields as well.
This is achieved by refactoring GHC.Rename.Env.lookupLocalTcNames, and
GHC.Rename.Env.lookupBindGroupOcc, to not look up a fixed number of
NameSpaces but to look up all NameSpaces and filter out the irrelevant
ones.

This commit consolidates all the logic for looking up something in
the Global Reader Environment into the single function lookupGRE.
This allows us to declaratively specify all the different modes of
looking up in the GlobalRdrEnv, and avoids manually passing around
filtering functions as was the case in e.g. the function
GHC.Rename.Env.lookupSubBndrOcc_helper.

This patch finally (I hope) nails the question of whether
(forall a. ty) and (forall a -> ty)
are `eqType`: they aren't!
There is a long discussion in #22762, plus useful Notes:
* Note [ForAllTy and type equality] in GHC.Core.TyCo.Compare
* Note [Comparing visiblities] in GHC.Core.TyCo.Compare
* Note [ForAllCo] in GHC.Core.TyCo.Rep
It also establishes a helpful new invariant for ForAllCo,
and ForAllTy, when the bound variable is a CoVar:in that
case the visibility must be coreTyLamForAllTyFlag.
All this is well documented in revised Notes.

Improved name resolution and type checking of type patterns in constructors:
1. HsTyPat: a new dedicated data type that represents type patterns in
HsConPatDetails instead of reusing HsPatSigType
2. rnHsTyPat: a new function that renames a type
pattern and collects its binders into three groups:
- explicitly bound type variables, excluding locally bound
variables
- implicitly bound type variables from kind signatures
(only if ScopedTypeVariables are enabled)
- named wildcards (only from kind signatures)
2a. rnHsPatSigTypeBindingVars: removed in favour of rnHsTyPat
2b. rnImplcitTvBndrs: removed because no longer needed
3. collect_pat: updated to collect type variable binders from type patterns
(this means that types and terms use the same infrastructure to detect
conflicting bindings, unused variables and name shadowing)
3a. CollVarTyVarBinders: a new CollectFlag constructor that enables
collection of type variables
4. tcHsTyPat: a new function that typechecks type patterns, capable of
handling polymorphic kinds.
See Note [Type patterns: binders and unifiers]
Examples of code that is now accepted:
f = \(P @a) -> \(P @a) -> ... -- triggers -Wname-shadowing

Commit e74fc066 refactored the handling of record updates to use
the HsExpanded mechanism. This meant that the pattern matching inherent
to a record update was considered to be "generated code", and thus we
stopped emitting "incomplete record update" warnings entirely.
This commit changes the "data Origin = Source | Generated" datatype,
adding a field to the Generated constructor to indicate whether we
still want to perform pattern-match checking. We also have to do a bit
of plumbing with HsCase, to record that the HsCase arose from an
HsExpansion of a RecUpd, so that the error message continues to mention
record updates as opposed to a generic "incomplete pattern matches in case"
error.
Finally, this patch also changes the way we handle inaccessible code
warnings. Commit e74fc066 was also a regression in this regard, as we
were emitting "inaccessible code" warnings for case statements spuriously
generated when desugaring a record update (remember: the desugaring mechanism
happens before typechecking; it thus can't take into account e.g. GADT information
in order to decide which constructors to include in the RHS of the desugaring
of the record update).
We fix this by changing the mechanism through which we disable inaccessible
code warnings: we now check whether we are in generated code in
GHC.Tc.Utils.TcMType.newImplication in order to determine whether to
emit inaccessible code warnings.

The preceding commit re-enabled pattern-match checking inside record
updates. This revealed that #21360 was in fact NOT fixed by e74fc066.
This commit makes sure we correctly propagate long-distance information
in do blocks, e.g. in
```haskell
data T = A { fld :: Int } | B
f :: T -> Maybe T
f r = do
a@A{} <- Just r
Just $ case a of { A _ -> A 9 }
```
we need to propagate the fact that "a" is headed by the constructor "A"
to see that the case expression "case a of { A _ -> A 9 }" cannot fail.

Some patterns introduce no new information to the pattern-match
checker (such as plain variable or wildcard patterns). We can thus
skip doing any pattern-match checking on them when the sole purpose
for doing so was introducing new long-distance information.
See Note [Boring patterns] in GHC.Hs.Pat.
Doing this avoids regressing in performance now that we do additional
pattern-match checking inside do notation.

This patch changes how we perform representation-polymorphism checking
for primops (and other wired-in Ids such as coerce).
When instantiating the primop, we check whether each type variable
is required to instantiated to a concrete type, and if so we create a
new concrete metavariable (a ConcreteTv) instead of a simple MetaTv.
(A little subtlety is the need to apply the substitution obtained from
instantiating to the ConcreteTvOrigins, see
Note [substConcreteTvOrigin] in GHC.Tc.Utils.TcMType.)
This allows us to prevent representation-polymorphism in non-argument
position, as that is required for some of these primops.
We can also remove the logic in tcRemainingValArgs, except for
the part concerning representation-polymorphic unlifted newtypes.
The function has been renamed rejectRepPolyNewtypes; all it does now
is reject unsaturated occurrences of representation-polymorphic newtype
constructors when the representation of its argument isn't a concrete
RuntimeRep (i.e. still a PHASE 1 FixedRuntimeRep check).
The Note [Eta-expanding rep-poly unlifted newtypes] in GHC.Tc.Gen.Head
gives more explanation about a possible path to PHASE 2, which would be
in line with the treatment for primops taken in this patch.
We also update the Core Lint check to handle this new framework. This
means Core Lint now checks representation-polymorphism in continuation
position like needed for catch#.

We are trying out a lighter weight validation pipeline where by default
we just test on 5 platforms:
* x86_64-deb10-slow-validate
* windows
* x86_64-fedora33-release
* aarch64-darwin
* aarch64-linux-deb10
In order to enable the "full" validation pipeline you can apply the
`full-ci` label which will enable all the validation pipelines.
All the validation jobs are still run on a marge batch.
The goal is to reduce the overall CI capacity so that pipelines start
faster for MRs and marge bot batches are faster.

The binutils documentation (for COFF) claims,
> If no flags are specified, the default flags depend upon the section
> name. If the section name is not recognized, the default will be for the
> section to be loaded and writable.
We previously assumed that this would do the right thing for split
sections (e.g. a section named `.text$foo` would be correctly inferred
to be a text section). However, we have observed that this is not the
case (at least under the clang toolchain used on Windows): when
split-sections is enabled, text sections are treated by the assembler as
data (matching the "default" behavior specified by the documentation).
Avoid this by setting section flags explicitly. This should fix split
sections on Windows.
Fixes #22834.
