<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Introduce OutputableP
Some types need a Platform value to be pretty-printed: CLabel, Cmm
types, instructions, etc.
Before this patch they had an Outputable instance and the Platform value
was obtained via sdocWithDynFlags. It meant that the *renderer* of the
SDoc was responsible of passing the appropriate Platform value (e.g. via
the DynFlags given to showSDoc). It put the burden of passing the
Platform value on the renderer while the generator of the SDoc knows the
Platform it is generating the SDoc for and there is no point passing a
different Platform at rendering time.
With this patch, we introduce a new OutputableP class:
class OutputableP a where
pdoc :: Platform -> a -> SDoc
With this class we still have some polymorphism as we have with `ppr`
(i.e. we can use `pdoc` on a variety of types instead of having a
dedicated `pprXXX` function for each XXX type).
One step closer removing `sdocWithDynFlags` (#10143) and supporting
several platforms (#14335).

Add a type parameter for the environment required by OutputableP. It

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts/nonmoving: Add missing STM write barrier
When updating a TRec for a TVar already part of a transaction we
previously neglected to add the old value to the update remembered set.
I suspect this was the cause of #18587.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Refactor foreign export tracking
This avoids calling `libc` in the initializers which are responsible for
registering foreign exports. We believe this should avoid the corruption
observed in #18548.
See Note [Tracking foreign exports] in rts/ForeignExports.c for an
overview of the new scheme.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Refactor unloading of foreign export StablePtrs
Previously we would allocate a linked list cell for each foreign export.
Now we can avoid this by taking advantage of the fact that they are
already broken into groups.
