addr2Int# and int2Addr# were marked as deprecated with the introduction
of the OCaml code generator (1dfaee318171836b32f6b33a14231c69adfdef2f)
due to its use of tagged integers. However, this backend has long
vanished and `base` has all along been using `addr2Int#` in the Show
instance for Ptr.

While it's unlikely that we will have another backend which has tagged
integers, we may indeed support platforms which have tagged pointers.
Consequently we undeprecate the operations but warn the user that the
operations may not be portable.

We use live words rather than live blocks to determine the size of the
heap for determining memory retention.

Most of the time these two metrics align, but they can come apart in
normal usage when using the nonmoving collector.

The nonmoving collector leads to a lot of partially occupied blocks. So,
using live words is more accurate.

They can also come apart when the heap is suffering from high levels
fragmentation caused by small pinned objects, but in this case, the
block size is the more accurate metric. Since this case is best avoided
anyway. It is ok to accept the trade-off that we might try (and
probably) fail to return more memory in this case.

See also the Note [Statistics for retaining memory]

Progress towards #21592

This splits HsSrcBang up, creating the new HsBang within
`Language.Haskell.Syntax.Basic`. `HsBang` holds the unpackedness
and strictness information, while `HsSrcBang` only adds the SourceText
for usage within the compiler directly.

Inside the AST, to preserve the SourceText, it is hidden behind the
pre-existing extension point `XBindTy`. All other occurrences of
`HsSrcBang` were adapted to deconstruct the inner `HsBang`, and when
interacting with the `BindTy` constructor, the hidden `SourceText` is
extracted/inserted into the `XBindTy` extension point.

`GHC.Core.DataCon` exports both `HsSrcBang` and `HsBang` for
convenience. A constructor function `mkHsSrcBang` that takes all
individual components has been added.

Two exceptions has been made though:
- The `Outputable HsSrcBang` instance is replaced by
  `Outputable HsBang`. While being only GHC-internal, the only place
  it's used is in outputting `HsBangTy` constructors -- which already
  have `HsBang`. It wouldn't make sense to reconstruct a `HsSrcBang` just
  to ignore the `SourceText` anyway.
- The error `TcRnUnexpectedAnnotation` did not use the `SourceText`,
  so it too now only holds a `HsBang`.

False` then it forces them to be built.

hadrian does not utilise the build-tool-depends fields in cabal files
and their presence can cause issues when building source distribution
(see #24826)

Ideally Cabal would support building "full" source distributions which
would remove the need for workarounds in hadrian but for now we can
patch the build-tool-depends out of the cabal files.

The main payload of this change is to hadrian.

* Default settings will produced dynamic profiled objects
* `-fexternal-interpreter` is turned on in some situations when there is
  an incompatibility between host GHC and the way attempting to be
  built.
* Very few changes actually needed to GHC

There are also necessary changes to the bootstrap plans to work with the
vendored Cabal dependency. These changes should ideally be reverted by
the next GHC release.

In hadrian support is added for building profiled dynamic libraries
(nothing too exciting to see there)

Updates hadrian to use a vendored Cabal submodule, it is important that
we replace this usage with a released version of Cabal library before
the 9.12 release.

There is some unexplained change to binding behaviour in python-3.12
which requires moving this import from the top-level into the scope of
the function.

I didn't feel any particular desire to do a deep investigation as to why
this changed as the code works when modified like this. No one in the
python IRC channel seemed to know what the problem was.

Use a deterministic unique map to back the implementation of `LabelMap`.

This is necessary towards the goal of object code determinism in #12935.

Our intended solution requires renaming uniques in a deterministic
order (which will be the order in which they were created), but storing
them label map makes us lose this order. Backing it with a UDFM fixes
this issue.

This MR adds one new defaulting strategy to the top-level
defaulting story: see Note [Defaulting equalities] in GHC.Tc.Solver.

This resolves #25029 and #25125, which showed that users were
accidentally relying on a GHC bug, which was fixed by

    commit 04f5bb85c8109843b9ac2af2a3e26544d05e02f4

    Fix untouchability test

    This MR fixes #24938.  The underlying problem was tha the test for
    "does this implication bring in scope any equalities" was plain wrong.

This fix gave rise to a number of user complaints; but the improved
defaulting story of this MR largely resolves them.

On the way I did a bit of refactoring, of course

* Completely restructure the extremely messy top-level defaulting
  code. The new code is in GHC.Tc.Solver.tryDefaulting, and is much,
  much, much esaier to grok.

* In GHC.Core.InstEnv, change the type synonym `Canonical` to a data
  type `CanonicalEvidence`; and document it better.  That in turn made
  me realise that CalLStacks were being treated with a bit of a hack, which
  I documented in `Note [CallStack and ExecptionContext hack]`.

* Fix a bug I found when desugaring RULE left hand sides; see (NC1) in
  Note [Desugaring non-canonical evidence] in GHC.HsToCore.Binds
  This means giving a boolean flag to dsHsWrapper, alas.  But I think it
  will go away again when I have finished with my (entirely separate)
  speciaise-on-values patch.

This reuses the upsweep step's infrastructure to process batches of
modules in parallel.

I benchmarked this by running `ghc -M` on two sets of 10,000 modules;
one with a linear dependency chain and the other with a binary tree.
Comparing different values for the number of modules per thread
suggested an optimum at `length targets `div` (n_cap * 2)`, with results
similar to this one (6 cores, 12 threads):

```
Benchmark 1: linear 1 jobs
  Time (mean ± σ):      1.775 s ±  0.026 s    [User: 1.377 s, System: 0.399 s]
  Range (min … max):    1.757 s …  1.793 s    2 runs

Benchmark 2: linear 6 jobs
  Time (mean ± σ):     876.2 ms ±  20.9 ms    [User: 1833.2 ms, System: 518.6 ms]
  Range (min … max):   856.2 ms … 898.0 ms    3 runs

Benchmark 3: linear 12 jobs
  Time (mean ± σ):     793.5 ms ±  23.2 ms    [User: 2318.9 ms, System: 718.6 ms]
  Range (min … max):   771.9 ms … 818.0 ms    3 runs
```

Results don't differ much when the batch size is reduced to a quarter
of that, but there's significant thread scheduling overhead for a size
of 1:

```
Benchmark 1: linear 1 jobs
  Time (mean ± σ):      2.611 s ±  0.029 s    [User: 2.851 s, System: 0.783 s]
  Range (min … max):    2.591 s …  2.632 s    2 runs

Benchmark 2: linear 6 jobs
  Time (mean ± σ):      1.189 s ±  0.007 s    [User: 2.707 s, System: 1.103 s]
  Range (min … max):    1.184 s …  1.194 s    2 runs

Benchmark 3: linear 12 jobs
  Time (mean ± σ):      1.097 s ±  0.006 s    [User: 2.938 s, System: 1.300 s]
  Range (min … max):    1.093 s …  1.101 s    2 runs
```

Larger batches also slightly worsen performance.
