<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">WinIO: Small changes related to atomic request swaps.
Move the atomix exchange over the Ptr type to an internal module.
Fix a bug caused by us passing ptr-to-ptr instead of ptr to
atomic exchange.
Renamed interlockedExchange to exchangePtr.
I've also added an cas primitive. It turned out we don't need it
for WinIO but I'm leaving it in as it's useful for other things.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: fix race condition in StgCRun
On windows the stack has to be allocated 4k at a time, otherwise we get
a segfault. This is done by using a helper ___chkstk_ms that is provided
by libgcc. The Haskell side already knows how to handle this but we need
to do the same from STG. Previously we would drop the stack in StgRun
but would only make it valid whenever the scheduler loop ran.
This approach was fundamentally broken in that it falls apart when you
take a signal from the OS. We see it less often because you initially
get allocated a 1MB stack block which you have to blow past first.
Concretely this means we must always keep the stack valid.
Fixes #18601.

Replace options like collect_stats(['peak_megabytes_allocated'],4) with
collect_runtime_residency(4) and so forth. Reason being that the later
also supplies some default RTS arguments which make sure residency does
not fluctuate too much.
The new flags mean we get new (hopefully more accurate) baselines so
accept the stat changes.

Previously we only matched on *variables* whose unfoldings were a ConApp
of the form `IS lit#` or `NS lit##`. But we forgot to match on the
ConApp directly... As a consequence, constant folding only worked after
the FloatOut pass which creates bindings for most sub-expressions. With
this patch, matching on bignums works even with -O0 (see bignumMatch
test).
