Before, `type DefUses = [DefUse]`. But lists are a terrible choice of
data structure here, as we frequently append to the right of a
`DefUses`, which yields some displeasing asymptotics. Let's instead
use `OrdList`, which has constant-time appending to the right.

This is one step on the way to #10347.

* Use show! in source tarball job. Since we aren't actually building
  anything in this job `show` won't
  work.

* Fix Docker image name

* Make `version` file contain only version string

Now that the target macros are not being used, we remove them. This
prevents target hardcoding regressions.

Since MR !1025 fixed the Windows build, allowing us to build a binary
distribution, we can now run the testsuite in that CI job.

This required fixing 'createFileLink': it should not try to create
symlinks on Windows (that requires admin priviledges, which Hadrian can't
assume). We now instead fall back to copying.

This patch also removes some duplicated logic for iserv in the test rules,
where we handle our dependency on the iserv binaries in a special way.

Now that we have absolute paths for submodules (since a76b233d) we no
longer need this script.

As fromFlag is partial. The only case where we used fromFlag is when
determining whether to strip libraries; we now assume that we shouldn't.

To display the free variables for a single breakpoint, GHCi pulls out the
information from the fields `modBreaks_breakInfo` and `modBreaks_vars`
of the `ModBreaks` data structure. For a specific breakpoint this gives 2
lists of types 'Id` (`Var`) and `OccName`. They are used to create the Id's
for the free variables and must be kept in sync:
If we remove an element from the Names list, then we also must remove the
corresponding element from the OccNames list.

Kqueue/kevent implementation used to ignore events to be unsubscribed
from when events to be subscribed to were provided. This resulted in a
lost notification subscription, when GHC runtime didn't listen for any
events, yet the kernel considered otherwise and kept waking up the IO
manager thread.

This commit fixes this issue by always adding and removing all of the
provided subscriptions.

This makes it simpler to load Modules importing it
when using ghc-the-package.

This commit fixes #16874 by using `fsep` rather than `sep` when pretty
printing long patterns and expressions.

This was requested in #15650.

This makes the `maintainer-clean` rule in `ghc.mk` slightly more
sophisticated so that it does not remove the version-controlled
file `libraries/ghc-boot/ghc.mk`, which was checked into version
control in commit 24782b89.

Fixes #16953.

9366e019 introduced a check for orphan roles to fix #8485

6ab5da99 changed the lookup code and made the check redundant.

Now it is removed.

As noted in #16909.

Fixed in #14759.

This requires code loading and therefore can't be run in the profiled
ways when GHC is dynamically linked.

As noted in #11645 and #8862, forking and profiling don't go well
together.

Bumps hpc and unix submodules.

Previously it was not marked as broken in profthreaded

As noted in #16914, the value `True` was used instead of `YES` here, in
contrast to the other boolean fields emitted by `--info`. This confused
the testsuite driver and broke the `ghc_debugged` testsuite predicate.

Otherwise the unique counter starts at 0, causing us to immediately
underflow.

See #16803.

This should help identify a few cases where this is throwing warnings

Otherwise we don't compile the stage2 compiler with DEBUG, meaning the
testsuite isn't checked with assertions.

By not building anything in the dynamic way on Windows, where we don't
have a working story for DLLs yet.

Also the ghcid command needs to call bash on the hadrian/ghci.sh script
explicitly as the path gets interpreted differently otherwise.
