ghci: only keep the GlobalRdrEnv in ModInfo

The datatype GHC.UI.Info.ModInfo used to store a ModuleInfo,
which includes a TypeEnv. This can easily cause space leaks as we
have no way of forcing everything in a type environment.

In GHC, we only use the GlobalRdrEnv, which we can force completely.
So we only store that instead of a fully-fledged ModuleInfo.

Add structured error messages for GHC.Tc.Utils.Backpack

Tracking ticket: #20119

MR: !10127

This converts uses of `mkTcRnUnknownMessage` to newly added constructors
of `TcRnMessage`.
One occurrence, when handing a nested error from the interface loading
machinery, was omitted. It will be handled by a subsequent changeset
that addresses interface errors.

Rename () into Unit, (,,...,,) into Tuple<n> (#21294)

This patch implements a part of GHC Proposal #475.
The key change is in GHC.Tuple.Prim:

  - data () = ()
  - data (a,b) = (a,b)
  - data (a,b,c) = (a,b,c)
  ...
  + data Unit = ()
  + data Tuple2 a b = (a,b)
  + data Tuple3 a b c = (a,b,c)
  ...

And the rest of the patch makes sure that Unit and Tuple<n>
are pretty-printed as () and (,,...,,) in various contexts.

Updates the haddock submodule.

Allow LLVM backend to use HDoc for faster file generation.

Also remove the MetaStmt constructor from LlvmStatement and places the annotations into the Store statement.

Includes “Implement a workaround for -no-asm-shortcutting bug“ (https://gitlab.haskell.org/ghc/ghc/-/commit/2fda9e0df886cc551e2cd6b9c2a384192bdc3045)

Compute LambdaFormInfo when using JavaScript backend.

CmmCgInfos is needed to write interface files, but the
JavaScript backend does not generate it, causing
"Name without LFInfo" warnings.

This patch adds a conservative but always correct
CmmCgInfos when the JavaScript backend is used.

Fixes #23053

Be more careful about quantification

This MR is driven by #23051. It does several things:

* It is guided by the generalisation plan described in #20686.
  But it is still far from a complete implementation of that plan.

* Add Note [Inferred type with escaping kind] to GHC.Tc.Gen.Bind.
  This explains that we don't (yet, pending #20686) directly
  prevent generalising over escaping kinds.

* In `GHC.Tc.Utils.TcMType.defaultTyVar` we default RuntimeRep
  and Multiplicity variables, beause we don't want to quantify over
  them.  We want to do the same for a Concrete tyvar, but there is
  nothing sensible to default it to (unless it has kind RuntimeRep,
  in which case it'll be caught by an earlier case). So we promote
  instead.

* Pure refactoring in GHC.Tc.Solver:
  * Rename decideMonoTyVars to decidePromotedTyVars, since that's
    what it does.

  * Move the actual promotion of the tyvars-to-promote from
    `defaultTyVarsAndSimplify` to `decidePromotedTyVars`.  This is a
    no-op; just tidies up the code.  E.g then we don't need to
    return the promoted tyvars from `decidePromotedTyVars`.

  * A little refactoring in `defaultTyVarsAndSimplify`, but no
    change in behaviour.

* When making a TauTv unification variable into a ConcreteTv
  (in GHC.Tc.Utils.Concrete.makeTypeConcrete), preserve the occ-name
  of the type variable.  This just improves error messages.

* Kill off dead code: GHC.Tc.Utils.TcMType.newConcreteHole

Refactor the constraint solver pipeline

The big change is to put the entire type-equality solver into
GHC.Tc.Solver.Equality, rather than scattering it over Canonical
and Interact.  Other changes

* EqCt becomes its own data type, a bit like QCInst.  This is
  great because EqualCtList is then just [EqCt]

* New module GHC.Tc.Solver.Dict has come of the class-contraint
  solver.  In due course it will be all.  One step at a time.

This MR is intended to have zero change in behaviour: it is a
pure refactor.  It opens the way to subsequent tidying up, we
believe.
