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.
