<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Improve handling of data type return kinds
Following a long conversation with Richard, this patch tidies up the
handling of return kinds for data/newtype declarations (vanilla,
family, and instance).
I have substantially edited the Notes in TyCl, so they would
bear careful reading.
Fixes #18300, #18357
In GHC.Tc.Instance.Family.newFamInst we were checking some Lint-like
properties with ASSSERT. Instead Richard and I have added
a proper linter for axioms, and called it from lintGblEnv, which in
turn is called in tcRnModuleTcRnM
New tests (T18300, T18357) cause an ASSERT failure in HEAD.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">add -flink-rts flag to link the rts when linking a shared or static library #18072
By default we don't link the RTS when linking shared libraries because in the
most usual mode a shared library is an intermediary product, for example a
Haskell library, that will be linked into some executable in the end. So we
wish to defer the RTS flavour to link to the final link.
However sometimes the final product is the shared library, for example when
writing a plugin for some other system, so we do wish the shared library to
link the RTS.
For consistency we also make -staticlib honor this flag and its inversion.
-staticlib currently implies -flink-shared.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">BigNum: rename BigNat types
Before this patch BigNat names were confusing because we had:
* GHC.Num.BigNat.BigNat: unlifted type used everywhere else
* GHC.Num.BigNat.BigNatW: lifted type only used to share static constants
* GHC.Natural.BigNat: lifted type only used for backward compatibility
After this patch we have:
* GHC.Num.BigNat.BigNat#: unlifted type
* GHC.Num.BigNat.BigNat: lifted type (reexported from GHC.Natural)
Thanks to @RyanGlScott for spotting this.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">winio: Clean up code surrounding IOPort primitives.
According to phyx these should only be read and written once per
object. Not neccesarily in that order.
To strengthen that guarantee the primitives will now throw an
exception if we violate this invariant.
As a consequence we can eliminate some code from their primops.
In particular code dealing with multiple queued readers/writers
now simply checks the invariant and throws an exception if it
was violated. That is in contrast to mvars which will do things
like wake up all readers, queue multi writers etc.

Multithreaded threadDelay suffered from a race condition
based on the ioManagerStatus. Since the status isn't needed
for WIO I removed it completely.
This resulted in a light refactoring, as consequence we will always
wake up the IO manager using interruptSystemManager, which uses
`postQueuedCompletionStatus` internally.
I also added a few comments which hopefully makes the code easier to
dive into for the next person diving in.

We now set a flag in the IO thread. The scheduler when looking for work
will check the flag and create/queue threads accordingly.
We used to create these in the IO thread. This improved performance
but caused frequent segfaults. Thread creation/allocation is only safe to
do if nothing currently accesses the storeagemanager. However without
locks in the non-threaded runtime this can't be guaranteed.
This shouldn't change performance all too much.
In the past we had:
* IO: Create/Queue thread.
* Scheduler: Runs a few times. Eventually picks up IO processing thread.
Now it's:
* IO: Set flag to queue thread.
* Scheduler: Pick up flag, if set create/queue thread. Eventually picks up IO processing thread.

We used a variable to keep track of situations where we got
entries from the IO port, but all of them had already been
canceled. While we can avoid some work that way this case
seems quite rare.
So we give up on tracking this and instead always assume at
least one of the returned entries is valid.
If that's not the case no harm is done, we just perform some
additional work. But it makes the runner easier to reason about.
In particular we don't need to care if another thread modifies
oustanding_requests after we return from waiting on the IO Port.
