is a better home for it. This change was discussed and approved by the CLC

This fixes an interaction between aging and weak pointer handling which
prevented the finalization of some weak pointers. In particular, weak
pointers could have their keys incorrectly marked by the preparatory
collector, preventing their finalization by the subsequent concurrent
collection.
While in the area, we also significantly improve the assertions
regarding weak pointers.
Fixes #22327.

Here we significantly improve the bound on sync phase pause times by

the mutators to resume, return to concurrent marking, and try
synchronizing again later.

The current segments are conceptually owned by the mutator, not the
collector. Consequently, it was quite tricky to prove that the mutator
would not race with the collect due to this shared state. It turns out
that such races are possible: when resizing the current segment array
we may concurrently try to take a heap census. This will attempt to walk
the current segment array, causing a data race.
Fix this by moving the current segment array into `Capability`, where it
belongs.

The nonmoving collector does not use `oldest_gen->blocks` to track its
block list. However, it nevertheless updates `oldest_gen->n_blocks` to
ensure that its size is accounted for by the storage manager.
Consequently, we must not attempt to assert consistency between the two.

!9193 pointed out that ghcDebugAssertions was supposed to be a predicate
on the stage of the built compiler, but in practice it was a predicate
on the stage of the compiler used to build. Unfortunately, while it
fixed that issue for ghcDebugAssertions, it documented every other
similar option as behaving the same way when in fact they all used the
old behavior.
The new behavior of ghcDebugAssertions seems more intuitive, so this
commit changes the interpretation of every other option to match. It
also improves the enableProfiledGhc and debugGhc flavour transformers by
making them more selective about which stages in which they build
additional library/RTS ways.

Previously the solver failed with an unhelpful "solver reached too may iterations" error.
With the fix for #21909 in place we no longer have the possibility of generating such an error if we have `-fconstraint-solver-iteration` > `-fgivens-fuel > `-fwanteds-fuel`. This is true by default, and the said fix also gives programmers a knob to control how hard the solver should try before giving up.
This commit adds:
* Reference to ticket #19627 in the Note [Expanding Recursive Superclasses and ExpansionFuel]
* Test `typecheck/should_fail/T19627.hs` for regression purposes

* Remove calls to 'setNumCapabilities' in 'createBCOs'
These calls exist to ensure that 'createBCOs' can benefit from
parallelism. But this is not the right place to call
`setNumCapabilities`. Furthermore the logic differs from that in the
driver causing the capability count to be raised and lowered at each TH
call if -j > -N.
* Remove 'BCOOpts'
No longer needed as it was only used to thread the job count down to `createBCOs`

Annoyingly, Darwin's <cstddef> includes <version> and APFS is
case-insensitive. Consequently, it will end up #including the
`VERSION` file generated by the `configure` script on the second
and subsequent runs of the `configure` script.
See #23116.</pre>

The datatype GHC.UI.Info.ModInfo used to store a ModuleInfo,
which includes a TypeEnv. This can easily cause space leaks as we
have no way of forcing everything in a type environment.
In GHC, we only use the GlobalRdrEnv, which we can force completely.
So we only store that instead of a fully-fledged ModuleInfo.

Tracking ticket: #20119
MR: !10127
This converts uses of `mkTcRnUnknownMessage` to newly added constructors
of `TcRnMessage`.
One occurrence, when handing a nested error from the interface loading
machinery, was omitted. It will be handled by a subsequent changeset
that addresses interface errors.

Previously the predicate for determining whether a logical instruction
operand could be encoded as a bitmask immediate was far too
conservative. This meant that, e.g., pointer untagged required five
instructions whereas it should only require one.
Fixes #23030.
