Resolves #22825
Now each diagnostic can name multiple different warning flags for its reason.
There is currently one use case: missing signatures.
Currently we need to check which warning flags are enabled when
generating the diagnostic, which is against the declarative nature of
the diagnostic framework.
This patch allows a warning diagnostic to have multiple warning flags,
which makes setup more declarative.
The WarningWithFlag pattern synonym is added for backwards compatibility
The 'msgEnvReason' field is added to MsgEnvelope to store the
`ResolvedDiagnosticReason`, which accounts for the enabled flags, and
then that is used for pretty printing the diagnostic.

When GHC invokes clang, it currently passes -Qunused-arguments to
discard warnings resulting from GHC using multiple options that aren't
used.
In this commit, we configure -Qunused-arguments into the Cc options
instead of checking if the compiler is clang at runtime and hardcoding
the flag into GHC.
This is part of the effort to centralise toolchain information in
toolchain target files at configure time with the end goal of a runtime
retargetable GHC.
This also means we don't need to call getCompilerInfo ever, which
improves performance considerably (see !10589).

Fixes #19692.
Prototypical cases:
class C1 a where
x1 :: a -> Int
data G1 = G1 deriving C1
class C2 a where
x2 :: a -> Int
x2 _ = 0
data G2 = G2 deriving C2
Both of these used to give this suggestion, but for C1 the suggestion
would have failed (generated code with undefined methods, which compiles
but warns). Now C2 still gives the suggestion but C1 doesn't.

GHC Proposal #425 "Invisible binders in type declarations" forbids
implicit quantification of type variables that occur free on the
right-hand side of a type synonym but are not mentioned on the left-hand side.
The users are expected to rewrite this using invisible binders:
type T1 :: forall a . Maybe a
type T1 = 'Nothing :: Maybe a -- old
type T1 @a = 'Nothing :: Maybe a -- new
Since the @k-binders are a new feature, we need to wait for three releases
before we require the use of the new syntax. In the meantime, we ought to
provide users with a new warning, -Wimplicit-rhs-quantification, that would
detect when such implicit quantification takes place, and include it in -Wcompat.

Prior to this change, `can_eq_nc` checked the visibility of the
outermost layer of foralls:
forall a. forall b. forall c. phi1
forall x. forall y. forall z. phi2
^^
up to here
Then it delegated the rest of the work to `can_eq_nc_forall`, which
split off all foralls:
forall a. forall b. forall c. phi1
forall x. forall y. forall z. phi2
^^
up to here
This meant that some visibility flags were completely ignored.
We fix this oversight by moving the check to `can_eq_nc_forall`.

Blocking IO used uninterruptibleMask which should make any thread
blocked on IO unreachable by async exceptions (such as those from
timeout). This changes it to a regular mask.
It's important to note that the nodejs runtime does not actually
interrupt the blocking IO when the Haskell thread receives an
async exception, and that file positions may be updated and buffers
may be written after the Haskell thread has already resumed.
Any file descriptor affected by an async exception interruption
should therefore be used with caution.

The Haskell runtime used to install a 'readable' handler on stdin
at startup in nodejs. This would cause the nodejs system to start
buffering the stream, causing data loss if the stdin file
descriptor is passed to another process.
This change delays installation of the 'readable' handler until
the first read of stdin by Haskell code.

This patch modifies the renamer to respect ScopedTypeVariables in kind
signatures. This means that kind variables bound by the outermost
`forall` now scope over the type:
type F = '[Right @a @() () :: forall a. Either a ()]
-- ^^^^^^^^^^^^^^^ ^^^
-- in scope here bound here
However, any use of such variables is a type error, because we don't
have type-level lambdas to bind them in Core. This is described in the
new Note [Type variable scoping errors during type check] in GHC.Tc.Types.

GHC Proposal #425 "Invisible binders in type declarations" restricts the
scope of type and data family instances as follows:
In type family and data family instances, require that every variable
mentioned on the RHS must also occur on the LHS.
For example, here are three equivalent type instance definitions accepted before this patch:
type family F1 a :: k
type instance F1 Int = Any :: j -> j
type family F2 a :: k
type instance F2 @(j -> j) Int = Any :: j -> j
type family F3 a :: k
type instance forall j. F3 Int = Any :: j -> j
- In F1, j is implicitly quantified and it occurs only on the RHS;
- In F2, j is implicitly quantified and it occurs both on the LHS and the RHS;
- In F3, j is explicitly quantified.
Now F1 is rejected with an out-of-scope error, while F2 and F3 continue to be accepted.

IPE data resulting from the `-finfo-table-map` flag may now be
compressed by configuring the GHC build with the
`--enable-ipe-data-compression` flag. This results in about a 20%
reduction in the size of IPE-enabled build results.
The compression library, zstd, may optionally be statically linked by
configuring with the `--enabled-static-libzstd` flag (on non-darwin
platforms)
libzstd version 1.4.0 or greater is required.

This prepares for having linear let expressions in the frontend.
When desugaring lets, SPECIALISE statements create more copies of a
let binding. Because of the rewrite rules attached to the bindings,
there are dependencies between the generated binds.
Before this commit, we simply wrapped all these in a mutually
recursive let block, and left it to the simplified to sort it out.
With this commit: we are careful to generate the bindings in
dependency order, so that we can wrap them in consecutive lets (if the
source is non-recursive).

Previously `shutdown_handler` would call `stg_exit` if the scheduler was
Oalready found to be in `SCHED_INTERRUPTING` state (or higher). However,
`stg_exit` is not signal-safe as it calls `exit` (which calls `atexit`
handlers). The only safe thing to do in this situation is to call
`_exit`, which terminates with minimal cleanup.

This requires changing the recomp007 test because now cabal passes
`this-unit-id` to executable components, and that unit-id contains a
hash which includes the ABI of the dependencies. Therefore changing the
dependencies means that -this-unit-id changes and recompilation is
triggered.
The spririt of the test is to test GHC's recompilation logic assuming
that `-this-unit-id` is constant, so we explicitly pass `-ipid` to
`./configure` rather than letting `Cabal` work it out.

Previously the `+werror` transformer would only pass `-Werror` to GHC,
which does not ensure that the same is passed to the C compiler when
building the RTS. Arguably this is itself a bug but for now we will just
work around this by passing `-optc-Werror` to GHC.
I tried to enable `-Werror` in all C compilations but the boot libraries
are something of a portability nightmare.

- Do not include `mi_globals` in the `NoBackend` backend. It was only included
for Haddock, but Haddock does not actually need it. This causes a 200MB
reduction in max residency when generating haddocks on the Agda codebase
(roughly 1GB to 800MB).
- Make haddock_{parser,renamer}_perf tests more accurate by forcing docs to
be written to interface files using `-fwrite-interface`
Bumps haddock submodule.
Metric Decrease:

For now it's only used by the JS interpreter but it could easily be used

This is an implementation of the deprecated exports proposal #134.
The proposal introduces an ability to introduce warnings to exports.
This allows for deprecating a name only when it is exported from a specific
module, rather than always depreacting its usage. In this example:
module A ({-# DEPRECATED "do not use" #-} x) where
x = undefined
---
module B where
import A(x)
`x` will emit a warning when it is explicitly imported.
Like the declaration warnings, export warnings are first accumulated within
the `Warnings` struct, then passed into the ModIface, from which they are
then looked up and warned about in the importing module in the `lookup_ie`
helpers of the `filterImports` function (for the explicitly imported names)
and in the `addUsedGRE(s)` functions where they warn about regular usages
of the imported name.
In terms of the AST information, the custom warning is stored in the
extension field of the variants of the `IE` type (see Trees that Grow for
more information).
The commit includes a bump to the haddock submodule added in MR #28

definitions, and (b) the prototypes appear only a few lines above. Work
