Make template-haskell a stage1 package
Promoting template-haskell from a stage0 to a stage1 package means that
we can much more easily refactor template-haskell.
We implement this by duplicating the in-tree `template-haskell`.
A new `template-haskell-next` library is autogenerated to mirror `template-haskell`
`stage1:ghc` to depend on the new interface of the library including the
`Binary` instances without adding an explicit dependency on `template-haskell`.
This is controlled by the `bootstrap-th` cabal flag
When building `template-haskell` modules as part of this vendoring we do
not have access to quote syntax, so we cannot use variable quote
notation (`'Just`). So we either replace these with hand-written `Name`s
or hide the code behind CPP.
We can remove the `th_hack` from hadrian, which was required when
building stage0 packages using the in-tree `template-haskell` library.
For more details see Note [Bootstrapping Template Haskell].

testsuite: Rename isCross() predicate to needsTargetWrapper()
isCross() was a misnamed because it assumed that all cross targets would
provide a target wrapper, but the two most common cross targets
(javascript, wasm) don't need a target wrapper.
Therefore we rename this predicate to `needsTargetWrapper()` so
situations in the testsuite where we can check whether running
executables requires a target wrapper or not.

Do not float HNFs out of lambdas
This MR adjusts SetLevels so that it is less eager to float a
HNF (lambda or constructor application) out of a lambda, unless
it gets to top level.
Data suggests that this change is a small net win:
* nofib bytes-allocated falls by -0.09% (but a couple go up)
* perf/should_compile bytes-allocated falls by -0.5%
* perf/should_run bytes-allocated falls by -0.1%
See !12410 for more detail.
When fiddling elsewhere, I also found that this patch had a huge
positive effect on the (very delicate) test
perf/should_run/T21839r
But that improvement doesn't show up in this MR by itself.

Make `seq#` a magic Id and inline it in CorePrep (#24124)
We can save much code and explanation in Tag Inference and StgToCmm by making
`seq#` a known-key Magic Id in `GHC.Internal.IO` and inline this definition in
CorePrep. See the updated `Note [seq# magic]`.
I also implemented a new `Note [Flatten case-bind]` to get better code for
otherwise nested case scrutinees.
I renamed the contructors of `ArgInfo` to use an `AI` prefix in order to
resolve the clash between `type CpeApp = CoreExpr` and the data constructor of
`ArgInfo`, as well as fixed typos in `Note [CorePrep invariants]`.
Fixes #24252 and #24124.

Remove unecessary stage0 packages
Historically quite a few packages had to be stage0 as they depended on
`template-haskell` and that was stage0. In #23536 we made it so that was
no longer the case. This allows us to remove a bunch of packages from
this list.
A few still remain. A new version of `Win32` is required by
`semaphore-compat`. Including `Win32` in the stage0 set requires also
including `filepath` because otherwise Hadrian's dependency logic gets
confused. Once our boot compiler has a newer version of `Win32` all of
these will be able to be dropped.

JS: Add externs to linker (fixes #24602)
After enabling jsdoc and built-in google closure compiler types I was needed to deal with the following:
1. Define NodeJS-environment types. I've just copied minimal set of externs from semi-official repo (see https://github.com/externs/nodejs/blob/6c6882c73efcdceecf42e7ba11f1e3e5c9c041f0/v8/nodejs.js#L8).
2. Define Emscripten-environment types: `HEAP8`. Emscripten already provides some externs in our code but it supposed to be run in some module system. And its definitions do not work well in plain bundle.
3. We have some functions which purpose is to add to functions some contextual information via function properties. These functions should be marked as `modifies` to let google closure compiler remove calls if these functions are not used actually by call graph. Such functions are: `h$o`, `h$sti`, `h$init_closure`, `h$setObjInfo`.
4. STG primitives such as registries and stuff from `GHC.StgToJS`. `dXX` properties were already present at externs generator function but they are started from `7`, not from `1`. This message is related: `// fixme does closure compiler bite us here?`

JS: Add special preprocessor for js files due of needing to keep jsdoc comments (fixes #24602)
Our js files have defined google closure compiler types at jsdoc entries but these jsdoc entries are removed by cpp preprocessor. I considered that reusing them in javascript-backend would be a nice thing. Right now haskell processor uses `-traditional` option to deal with comments and `//` operators.
But now there are following compiler options: `-C` and `-CC`.
You can read about them at GCC (see https://gcc.gnu.org/onlinedocs/gcc/Preprocessor-Options.html#index-CC) and CLang (see https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-CC).
It seems that `-CC` works better for javascript jsdoc than `-traditional`.
At least it leaves `/* ... */` comments w/o changes.

Typecheck corebindings lazily during bytecode generation
This delays typechecking the corebindings until the bytecode generation
happens.
We also avoid allocating a thunk that is retained by `unsafeInterleaveIO`.
In general, we shouldn't retain values of the hydrated `Type`, as not evaluating
the bytecode object keeps it alive.
It is better if we retain the unhydrated `IfaceType`.

driver: force merge objects when building dynamic objects
This patch forces the driver to always merge objects when building
dynamic objects even when ar -L is supported. It is an oversight of
!8887: original rationale of that patch is favoring the relatively
cheap ar -L operation over object merging when ar -L is supported,
which makes sense but only if we are building static objects! Omitting
check for whether we are building dynamic objects will result in
broken .so files with undefined reference errors at executable link
time when building GHC with llvm-ar. Fixes #22210.

Refactor the Binary serialisation interface
The goal is simplifiy adding deduplication tables to `ModIface`
interface serialisation.
We identify two main points of interest that make this difficult:
1. UserData hardcodes what `Binary` instances can have deduplication
tables. Moreover, it heavily uses partial functions.
2. GHC.Iface.Binary hardcodes the deduplication tables for 'Name' and
'FastString', making it difficult to add more deduplication.
Instead of having a single `UserData` record with fields for all the
types that can have deduplication tables, we allow to provide custom
serialisers for any `Typeable`.
These are wrapped in existentials and stored in a `Map` indexed by their
respective `TypeRep`.
The `Binary` instance of the type to deduplicate still needs to
explicitly look up the decoder via `findUserDataReader` and
`findUserDataWriter`, which is no worse than the status-quo.
`Map` was chosen as microbenchmarks indicate it is the fastest for a
small number of keys (< 10).
To generalise the deduplication table serialisation mechanism, we
introduce the types `ReaderTable` and `WriterTable` which provide a
simple interface that is sufficient to implement a general purpose
deduplication mechanism for `writeBinIface` and `readBinIface`.
This allows us to provide a list of deduplication tables for
serialisation that can be extended more easily, for example for
`IfaceTyCon`, see the issue https://gitlab.haskell.org/ghc/ghc/-/issues/24540
for more motivation.
In addition to this refactoring, we split `UserData` into `ReaderUserData`
and `WriterUserData`, to avoid partial functions and reduce overall
memory usage, as we need fewer mutable variables.
Bump haddock submodule to accomodate for `UserData` split.

Split `BinHandle` into `ReadBinHandle` and `WriteBinHandle`
A `BinHandle` contains too much information for reading data.
For example, it needs to keep a `FastMutInt` and a `IORef BinData`,
when the non-mutable variants would suffice.
Additionally, this change has the benefit that anyone can immediately
tell whether the `BinHandle` is used for reading or writing.
Bump haddock submodule BinHandle split.

Fix missing escaping-kind check in tcPatSynSig
Note [Escaping kind in type signatures] explains how we deal
with escaping kinds in type signatures, e.g.
f :: forall r (a :: TYPE r). a
where the kind of the body is (TYPE r), but `r` is not in
scope outside the forall-type.
