It is better to keep these scripts in the tree as they depend on the CI
configuration and so on. By keeping them in tree we can keep them
up-to-date as the CI config changes and also makes it easier to backport
changes to the release script between release branches in future.
The final motivation is that it makes generating GHCUp metadata
possible.

1. A python script in .gitlab/rel_eng/mk-ghcup-metadata which generates
suitable metadata for consumption by GHCUp for the relevant
pipelines.
- The script generates the metadata just as the ghcup maintainers
want, without taking into account platform/library combinations. It
is updated manually when the mapping changes.
- The script downloads the bindists which ghcup wants to distribute,
calculates the hash and generates the yaml in the correct structure.
- The script is documented in the .gitlab/rel_eng/mk-ghcup-metadata/README.mk file
1a. The script requires us to understand the mapping from platform ->
job. To choose the preferred bindist for each platform the
.gitlab/gen_ci.hs script is modified to allow outputting a metadata
file which answers the question about which job produces the
bindist which we want to distribute to users for a specific
platform.
2. Pipelines to run on nightly and release jobs to generate metadata
- ghcup-metadata-nightly: Generates metadata which points directly to
artifacts in the nightly job.
- ghcup-metadata-release: Generates metadata suitable for inclusion
directly in ghcup by pointing to the downloads folder where the
bindist will be uploaded to.
2a. Trigger jobs which test the generated metadata in the downstream
`ghccup-ci` repo. See that repo for documentation about what is
tested and how but essentially we test in a variety of clean images
that ghcup can download and install the bindists we say exist in our
metadata.

This fixes a tricky leak in GHCi where we were retaining old copies of
HscEnvs when reloading. If not all modules were recompiled then these
hydrated fields in break points would retain a reference to the old
HscEnv which could double memory usage.

Doesn't force the lazy `OccName` field (#19619) which is already known
as a really bad source of leaks.
When we slam the hammer storing Names on disk (in interface files or the
like), all this should be forced as otherwise a `Name` can easily retain
an `Id` and hence the entire world.

Problem: In 2463df2f, the Solo data constructor was renamed to MkSolo,
and Solo was turned into a pattern synonym for backwards compatibility.
Since pattern synonyms can not be promoted, the old code that pretty-printed
promoted single-element tuples started producing ill-typed code:
t :: Proxy ('Solo Int)
This fails with "Pattern synonym ‘Solo’ used as a type"
The solution is to track the distinction between type constructors and data
constructors more carefully when printing single-element tuples.

Following the plan in GHC Proposal #143 "Remove the * kind syntax",
which states:
In the next release (or 3 years in), enable -fwarn-star-is-type by default.
The "next release" happens to be 9.6.1
I also moved the T21583 test case from should_fail to should_compile,
because the only reason it was failing was -Werror=compat in our test
suite configuration.
