Big TcLclEnv and CtLoc refactoring
The overall goal of this refactoring is to reduce the dependency
footprint of the parser and syntax tree. Good reasons include:
- Better module graph parallelisability
- Make it easier to migrate error messages without introducing module loops
- Philosophically, there's not reason for the AST to depend on half the
compiler.
One of the key edges which added this dependency was
> GHC.Hs.Expr -> GHC.Tc.Types (TcLclEnv)
As this in turn depending on TcM which depends on HscEnv and so on.
Therefore the goal of this patch is to move `TcLclEnv` out of
`GHC.Tc.Types` so that `GHC.Hs.Expr` can import TcLclEnv without
incurring a huge dependency chain.
The changes in this patch are:
* Move TcLclEnv from GHC.Tc.Types to GHC.Tc.Types.LclEnv
* Create new smaller modules for the types used in TcLclEnv
New Modules:
- GHC.Tc.Types.ErrCtxt
- GHC.Tc.Types.BasicTypes
- GHC.Tc.Types.TH
- GHC.Tc.Types.LclEnv
- GHC.Tc.Types.CtLocEnv
- GHC.Tc.Errors.Types.PromotionErr
Removed Boot File:
- {-# SOURCE #-} GHC.Tc.Types
* Introduce TcLclCtxt, the part of the TcLclEnv which doesn't
participate in restoreLclEnv.
* Replace TcLclEnv in CtLoc with specific CtLocEnv which is defined in
GHC.Tc.Types.CtLocEnv. Use CtLocEnv in Implic and CtLoc to record the
location of the implication and constraint.
By splitting up TcLclEnv from GHC.Tc.Types we allow GHC.Hs.Expr to no
longer depend on the TcM monad and all that entails.
Fixes #23389 #23409

Remove dependency of GHC.Tc.Utils.TcType on GHC.Driver.Session
This removes the usage of DynFlags from Tc.Utils.TcType so that it no
longer depends on GHC.Driver.Session. In general we don't want anything
which is a dependency of Language.Haskell.Syntax to depend on
GHC.Driver.Session and removing this edge gets us closer to that goal.

Move isIrrefutableHsPat to GHC.Rename.Utils and rename to isIrrefutableHsPatRn
This removes edge from GHC.Hs.Pat to GHC.Driver.Session, which makes
Language.Haskell.Syntax end up depending on GHC.Driver.Session.

hole fit plugins: Split definition into own module
The hole fit plugins are defined in terms of TcM, a type we want to
avoid depending on from `GHC.Tc.Errors.Types`. By moving it into its own
module we can remove this dependency. It also simplifies the necessary
boot file.

Move GHC.Core.Opt.CallerCC Types into separate module
This allows `GHC.Driver.DynFlags` to depend on these types without
depending on CoreM and hence the entire simplifier pipeline.
We can also remove a hs-boot file with this change.

testsuite: Accept new output for CountDepsAst and CountDepsParser tests
These are in a separate commit as the improvement to these tests is the
cumulative effect of the previous set of patches rather than just the
responsibility of the last one in the patchset.

TTG: only allow VarBind at GhcTc
The VarBind constructor of HsBind is only used at the GhcTc stage.
This commit makes that explicit by setting the extension field of
VarBind to be DataConCantHappen at all other stages.
This allows us to delete a dead code path in GHC.HsToCore.Quote.rep_bind,
and remove some panics.

Generate Addr# access ops programmatically
The existing utils/genprimopcode/gen_bytearray_ops.py was
relocated and extended for this purpose. Additionally, hadrian
now knows about this script and uses it when generating primops.txt

ghcup-metadata: Only add Nightly tag when replacing LatestNightly
Previously we were always adding the Nightly tag, but this led to all
the previous builds getting an increasing number of nightly tags over
time. Now we just add it once, when we remove the LatestNightly tag.

Invisible binders in type declarations (#22560)
This patch implements @k-binders introduced in GHC Proposal #425
and guarded behind the TypeAbstractions extension:
type D :: forall k j. k -> j -> Type
data D @k @j a b = ...
^^ ^^
To represent the new syntax, we modify LHsQTyVars as follows:
- hsq_explicit :: [LHsTyVarBndr () pass]
+ hsq_explicit :: [LHsTyVarBndr (HsBndrVis pass) pass]
HsBndrVis is a new data type that records the distinction between
type variable binders written with and without the @ sign:
data HsBndrVis pass
= HsBndrRequired
| HsBndrInvisible (LHsToken "@" pass)
The rest of the patch updates GHC, template-haskell, and haddock
to handle the new syntax.
Parser:
The PsErrUnexpectedTypeAppInDecl error message is removed.
The syntax it used to reject is now permitted.
Renamer:
The @ sign does not affect the scope of a binder, so the changes to
the renamer are minimal. See rnLHsTyVarBndrVisFlag.
Type checker:
There are three code paths that were updated to deal with the newly
introduced invisible type variable binders:
1. checking SAKS: see kcCheckDeclHeader_sig, matchUpSigWithDecl
2. checking CUSK: see kcCheckDeclHeader_cusk
3. inference: see kcInferDeclHeader, rejectInvisibleBinders
Helper functions bindExplicitTKBndrs_Q_Skol and bindExplicitTKBndrs_Q_Tv
are generalized to work with HsBndrVis.
Updates the haddock submodule.

Extension shuffling (#23291)
Where introduced 3 new extensions:
- PatternSignatures
- ExtendedForAllScope
- MethodTypeVariables
Tasks of ScopedTypeVariables extension were distributed between
PatternSignatures, ExtendedForAllScope and MethodTypeVariables according
to the proposal. Now ScopedTypeVaribles only implies these three exntesions.
