Setting a larger stack chunk size gives a greater protection
from stack thrashing (where the repeated overflow/underflow allocates a lot of
stack chunks which sigificantly impact allocations). This
stabilises some tests against differences cause by more things being
pushed onto the stack.
The performance tests are generally testing work done by the compiler,
using allocation as a proxy, so removing/stabilising the allocations due
to the stack gives us more stable tests which are also more sensitive
to actual changes in compiler performance.
The tests which increase are ones where we compile a lot of modules, and
for each module we spawn a thread to compile the module in. Therefore
increasing these numbers has a multiplying effect on these tests because
there are many more stacks which we can increase in size.
The most significant improvements though are cases such as T8095 which
reduce significantly in allocations (30%). This isn't a performance
improvement really but just helps stabilise the test against this
threshold set by the defaults.

This commit splits up the zonker into a few separate components, described
in Note [The structure of the zonker] in `GHC.Tc.Zonk.Type`.
1. `GHC.Tc.Zonk.Monad` introduces a pared-down `TcM` monad, `ZonkM`,
which has enough information for zonking types.
This allows us to refactor `ErrCtxt` to use `ZonkM` instead of `TcM`,
which guarantees we don't throw an error while reporting an error.
2. `GHC.Tc.Zonk.Env` is the new home of `ZonkEnv`, and also defines
two zonking monad transformers, `ZonkT` and `ZonkBndrT`.
`ZonkT` is a reader monad transformer over `ZonkEnv`.
`ZonkBndrT m` is the codensity monad over `ZonkT m`.
`ZonkBndrT` is used for computations that accumulate binders
in the `ZonkEnv`.
3. `GHC.Tc.Zonk.TcType` contains the code for zonking types, for use
in the typechecker. It uses the `ZonkM` monad.
4. `GHC.Tc.Zonk.Type` contains the code for final zonking to `Type`,
which has been refactored to use `ZonkTcM = ZonkT TcM` and
`ZonkBndrTcM = ZonkBndrT TcM`.
Allocations slightly decrease on the whole due to using
continuation-passing style instead of manual state passing of ZonkEnv
in the final zonking to Type.

Reference ticket #21766
This commit restructures IPE buffer list entries to not contain
references to their corresponding info tables. IPE buffer list nodes now
point to two lists of equal length, one holding the list of info table
pointers and one holding the corresponding entries for each info table.
This will allow the entry data to be compressed without losing the
references to the info tables.

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.

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.

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.
