compiler/Types: Ensure that fromList-type operations can fuse

In #20740 I noticed that mkUniqSet does not fuse. In practice, allowing
it to do so makes a considerable difference in allocations due to the
backend.

x86 CodeGen: MO_S_MulMayOflo better error message for rep > W64

It's useful to see which value made the pattern match fail. (If it ever
occurs.)

x86 CodeGen: Implement MO_S_MulMayOflo for W8

This case wasn't handled before. But, the test-primops test suite showed
that it actually might appear.

Add test for %mulmayoflo primop

The test expects a perfect implementation with no false positives.

lint-ci-config: Generate jobs-metadata.json

We also now save the jobs-metadata.json and jobs.yaml file as artifacts
as:

* It might be useful for someone who is modifying CI to copy jobs.yaml
  if they are having trouble regenerating locally.
* jobs-metadata.json is very useful for downstream pipelines to work out
  the right job to download.

Fixes #23654

Prioritise Parent when looking up class sub-binder

When we look up children GlobalRdrElts of a given Parent, we sometimes
would rather prioritise those GlobalRdrElts which have the right Parent,
and sometimes prioritise those that have the right NameSpace:

  - in export lists, we should prioritise NameSpace
  - for class/instance binders, we should prioritise Parent

See Note [childGREPriority] in GHC.Types.Name.Reader.

fixes #23664

EPA: Improve annotation management in getMonoBind

Ensure the LHsDecl for a FunBind has the correct leading comments and
trailing annotations.

Visible forall in types of terms: Part 1

This patch implements part 1 of GHC Proposal #281,
introducing explicit `type` patterns and `type` arguments.

Summary of the changes:

1. New extension flag:
     RequiredTypeArguments

2. New user-facing syntax:
     `type p` patterns    (represented by EmbTyPat)
     `type e` expressions (represented by HsEmbTy)

3. Functions with required type arguments (visible forall)
   can now be defined and applied:
      idv :: forall a -> a -> a    -- signature   (relevant change: checkVdqOK in GHC/Tc/Validity.hs)
      idv (type a) (x :: a) = x    -- definition  (relevant change: tcPats in GHC/Tc/Gen/Pat.hs)
      x = idv (type Int) 42        -- usage       (relevant change: tcInstFun in GHC/Tc/Gen/App.hs)

4. template-haskell support:
      TH.TypeE corresponds to HsEmbTy
      TH.TypeP corresponds to EmbTyPat

5. Test cases and a new User's Guide section

Changes *not* included here are the t2t (term-to-type) transformation
and term variable capture; those belong to part 2.
