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.
Fixes #21360

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#.

When we look up children GlobalRdrElts of a given Parent, we sometimes
would rather prioritise those GlobalRdrElts which have the right Parent,
and sometimes prioritise those that have the right NameSpace:
- in export lists, we should prioritise NameSpace
- for class/instance binders, we should prioritise Parent
See Note [childGREPriority] in GHC.Types.Name.Reader.

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.

When the Win32 threaded IO manager shuts down, `ioManagerDie` sends an
`IO_MANAGER_DIE` event to the IO manager thread using the
`io_manager_event` event object. Finally, it will closes the event object,
and invalidate `io_manager_event`.
Previously, `readIOManagerEvent` would see that `io_manager_event` is
invalid and return `0`, suggesting that everything is right with the
world. This meant that if `ioManagerDie` invalidated the handle before
the event manager was blocked on the event we would end up in a
situation where the event manager would never realize it was asked to
shut down.
Fix this by ensuring that `readIOManagerEvent` instead returns
`IO_MANAGER_DIE` when we detect that the event object has been
invalidated by `ioManagerDie`.
Fixes #23691.
