This delays typechecking the corebindings until the bytecode generation
happens.
We also avoid allocating a thunk that is retained by `unsafeInterleaveIO`.
In general, we shouldn't retain values of the hydrated `Type`, as not evaluating
the bytecode object keeps it alive.
It is better if we retain the unhydrated `IfaceType`.

This patch forces the driver to always merge objects when building
dynamic objects even when ar -L is supported. It is an oversight of
!8887: original rationale of that patch is favoring the relatively
cheap ar -L operation over object merging when ar -L is supported,
which makes sense but only if we are building static objects! Omitting
check for whether we are building dynamic objects will result in
broken .so files with undefined reference errors at executable link
time when building GHC with llvm-ar. Fixes #22210.

The goal is simplifiy adding deduplication tables to `ModIface`
interface serialisation.
We identify two main points of interest that make this difficult:
1. UserData hardcodes what `Binary` instances can have deduplication
tables. Moreover, it heavily uses partial functions.
2. GHC.Iface.Binary hardcodes the deduplication tables for 'Name' and
'FastString', making it difficult to add more deduplication.
Instead of having a single `UserData` record with fields for all the
types that can have deduplication tables, we allow to provide custom
serialisers for any `Typeable`.
These are wrapped in existentials and stored in a `Map` indexed by their
respective `TypeRep`.
The `Binary` instance of the type to deduplicate still needs to
explicitly look up the decoder via `findUserDataReader` and
`findUserDataWriter`, which is no worse than the status-quo.
`Map` was chosen as microbenchmarks indicate it is the fastest for a
small number of keys (< 10).
To generalise the deduplication table serialisation mechanism, we
introduce the types `ReaderTable` and `WriterTable` which provide a
simple interface that is sufficient to implement a general purpose
deduplication mechanism for `writeBinIface` and `readBinIface`.
This allows us to provide a list of deduplication tables for
serialisation that can be extended more easily, for example for
`IfaceTyCon`, see the issue https://gitlab.haskell.org/ghc/ghc/-/issues/24540
for more motivation.
In addition to this refactoring, we split `UserData` into `ReaderUserData`
and `WriterUserData`, to avoid partial functions and reduce overall
memory usage, as we need fewer mutable variables.
Bump haddock submodule to accomodate for `UserData` split.

A `BinHandle` contains too much information for reading data.
For example, it needs to keep a `FastMutInt` and a `IORef BinData`,
when the non-mutable variants would suffice.
Additionally, this change has the benefit that anyone can immediately
tell whether the `BinHandle` is used for reading or writing.
Bump haddock submodule BinHandle split.

Note [Escaping kind in type signatures] explains how we deal
with escaping kinds in type signatures, e.g.
f :: forall r (a :: TYPE r). a
where the kind of the body is (TYPE r), but `r` is not in
scope outside the forall-type.
I had missed this subtlety in tcPatSynSig, leading to #24686.
This MR fixes it; and a similar bug in tc_top_lhs_type. (The
latter is tested by T24686a.)

Closes https://gitlab.haskell.org/ghc/ghc/-/issues/24288, implements CLC
proposal https://github.com/haskell/core-libraries-committee/issues/238.
Adds a MonadFix instance for tuples, permitting value recursion in the
"native" writer monad and bringing consistency with the existing
instance for transformers's WriterT (and, to a lesser extent, for Solo).

The original fix (725343aa) was incorrect because it used the shell
bracket syntax which is the quoting syntax in autoconf, making the test
for existence be incorrect and therefore `xattr` was never run.
Fixes #24554

This patch enables wasm jobs for MRs with wasm label. Previously the
wasm label didn't actually have any effect on the CI pipeline, and
full-ci needed to be applied to run wasm jobs which was a waste of
runners when working on the wasm backend, hence the fix here.

When `framework_fail` is called before initialising testdir, it would fail with

Ensure we report the actual reason for the failure instead of failing in this way.
One way this can manifest is when trying to run a test that doesn't exist using `--only`

* Don't lock tvars when performing non-committal validation.

This prevents in-flight validation from failing spuriously if it happens in

When a breakpoint is inlined, its context may change (e.g. tyvars in

index as its sole identifier. Each instance of a breakpoint (even with
the same tick index) now gets a different "info" index.
We also need to distinguish modules:

- info module: module having the CgBreakInfo (info at occurrence site)

Unboxed sum constructors are now defined in the `GHC.Types` module, so if you
manually quote an unboxed sum (e.g., `''Sum2#`), you will get a `Name` like:
```hs
GHC.Types.Sum2#
```
The `unboxedSumTypeName` function in `template-haskell`, however, mistakenly
believes that unboxed sum constructors are defined in `GHC.Prim`, so
`unboxedSumTypeName 2` would return an entirely different `Name`:
```hs
GHC.Prim.(#|#)
```
This is a problem for Template Haskell users, as it means that they can't be
sure which `Name` is the correct one. (Similarly for `unboxedSumDataName`.)
This patch fixes the implementations of `unboxedSum{Type,Data}Name` to use
`GHC.Types` as the module. For consistency with `unboxedTupleTypeName`, the
`unboxedSumTypeName` function now uses the non-punned syntax for unboxed sums
(`Sum<N>#`) as the `OccName`.
Fixes #24750.

A future C-- test called T24474-cmm-override-g0 relies on the
GCC-specific behaviour of -g3 implying -dD, which, in turn, leads to it
emitting #defines past the preprocessing stage. Clang, at least, does
not do this, so the test would fail if ran on Clang.
As the behaviour here being tested is ``-optCmmP-g3'' undoing effects of
the workaround we apply as a fix for bug #24474, and the workaround was
for GCC-specific behaviour, the test needs to be marked as fragile on
other compilers.

Previously, C-- was processed with the C preprocessor program. This
means that it inherited flags passed via -optc. A flag that is somewhat
often passed through -optc is -g. At certain -g levels (>=2), GCC
starts emitting defines *after* preprocessing, for the purposes of
debug info generation. This is not useful for the C-- compiler, and, in
fact, causes lexer errors. We can suppress this effect (safely, if
supported) via -g0.
As a workaround, in older versions of GCC (<=10), GCC only emitted
defines if a certain set of -g*3 flags was passed. Newer versions check
the debug level. For the former, we filter out those -g*3 flags and,
for the latter, we specify -g0 on top of that.
As a compatible and effective solution, this change adds a C--
preprocessor distinct from the C compiler and preprocessor, but that
keeps its flags. The command line produced for C-- preprocessing now
looks like:
$pgmCmmP $optCs_without_g3 $g0_if_supported $optCmmP

We used to reject LHS like `(f a) b` in RULES and requires it to be written as
`f a b`. It will be handy to allow both as the expression may be more
readable with extra parens in some cases when infix operator is involved.
Espceially when TemplateHaskell is used, extra parens may be added out of
user's control and result in "valid" rules being rejected and there
are not always ways to workaround it.

This patch improves the algorithm to sort lists in base.
It does so using two strategies:
1) Use a four-way-merge instead of the 'default' two-way-merge.
This is able to save comparisons and allocations.
2) Use `(>) a b` over `compare a b == GT` and allow inlining and specialization.
This mainly benefits types with a fast (>).
Note that this *may* break instances with a *malformed* Ord instance
where `a > b` is *not* equal to `compare a b == GT`.

GHCi only needs the `mi_globals` field for modules imported with
:module +*SomeModule.
It uses this field to make the top level environment in `SomeModule` available
to the repl.
By default, only the first target in the command line parameters is
"star" loaded into GHCi. Other modules have to be manually "star" loaded
into the repl.
Storing the top level GlobalRdrEnv for each module is very wasteful, especially
given that we will most likely never need most of these environments.
Instead we store only the information needed to reconstruct the top level environment
in a module, which is the `IfaceTopEnv` data structure, consisting of all import statements
as well as all top level symbols defined in the module (not taking export lists into account)
When a particular module is "star-loaded" into GHCi (as the first commandline target, or via
an explicit `:module +*SomeModule`, we reconstruct the top level environment on demand using
the `IfaceTopEnv`.

`pat_to_type_pat` function now can handle more patterns:
- TuplePat
- ListPat
- LitPat
- NPat
- ConPat
Allowing these new constructors in type patterns significantly
increases possible shapes of type patterns without `type` keyword.
This patch also changes how lookups in `lookupOccRnConstr` are
performed, because we need to fall back into
types when we didn't find a constructor on data level to perform
`ConPat` to type transformation properly.
