Detect family instance orphans correctly
We were treating a type-family instance as a non-orphan if there
was a type constructor on its /right-hand side/ that was local. Boo!
Utterly wrong. With this patch, we correctly check the /left-hand side/
instead!
Fixes #22717

Report family instance orphans correctly
This fixes the fact that we were not reporting orphan family instances
at all. The fix here is easy, but touches a bit of code. I refactored
the code to be much more similar to the way that class instances are done:
- Add a fi_orphan field to FamInst, like the is_orphan field in ClsInst
- Make newFamInst initialise this field, just like newClsInst
- And make newFamInst report a warning for an orphan, just like newClsInst
- I moved newFamInst from GHC.Tc.Instance.Family to GHC.Tc.Utils.Instantiate,
just like newClsInst.
- I added mkLocalFamInst to FamInstEnv, just like mkLocalClsInst in InstEnv
- TcRnOrphanInstance and SuggestFixOrphanInstance are now parametrised
over class instances vs type/data family instances.
Fixes #19773

Avoid orphans in STG
This patch removes some orphan instances in the STG namespace
by introducing the GHC.Stg.Lift.Types module, which allows various
type family instances to be moved to GHC.Stg.Syntax, avoiding orphan
instances.

Avoid orphans in the parser
This moves Anno instances for PatBuilder from GHC.Parser.PostProcess
to GHC.Parser.Types to avoid orphans.

Accept an orphan declaration (sadly)
This accepts the orphan type family instance
type instance DsForeignHook = ...
in GHC.HsToCore.Types.

testsuite: Introduce threaded2_sanity way
Incredibly, we previously did not have a single way which would test the
threaded RTS with multiple capabilities and the sanity-checker enabled.

rts: Relax Messages assertion
`doneWithMsgThrowTo` was previously too strict in asserting that the
`Message` is locked. Specifically, it failed to consider that the
`Message` may not be locked if we are deleting all threads during RTS
shutdown.

testsuite: Fix race in UnliftedTVar2
Previously UnliftedTVar2 would fail when run with multiple capabilities
(and possibly even with one capability) as it would assume that
`killThread#` would immediately kill the "increment" thread.
Also, refactor the the executable to now succeed with no output and
fails with an exit code.

testsuite: Make listThreads more robust
Previously it was sensitive to the labels of threads which it did not
create (e.g. the IO manager event loop threads). Fix this.

CApiFFI: add ConstPtr for encoding const-qualified pointer return types
Previously, when using `capi` calling convention in foreign declarations,
code generator failed to handle const-cualified pointer return types.
This resulted in CC toolchain throwing `-Wincompatible-pointer-types-discards-qualifiers`
warning.
`Foreign.C.Types.ConstPtr` newtype was introduced to handle these cases -
special treatment was put in place to generate appropritetly qualified C
wrapper that no longer triggers the above mentioned warning.
Fixes #22043.

Convert diagnostics in GHC.Rename.Bind to proper TcRnMessage (#20115)
I removed all occurrences of TcRnUnknownMessage in GHC.Rename.Bind
module. Instead, these TcRnMessage messages were introduced:
TcRnMultipleFixityDecls
TcRnIllegalPatternSynonymDecl
TcRnIllegalClassBiding
TcRnOrphanCompletePragma
TcRnEmptyCase
TcRnNonStdGuards
TcRnDuplicateSigDecl
TcRnMisplacedSigDecl
TcRnUnexpectedDefaultSig
TcRnBindInBootFile
TcRnDuplicateMinimalSig

hadrian: Fix library-dirs, dynamic-library-dirs and static-library-dirs in inplace .conf files
Previously we were just throwing away the contents of the library-dirs
fields but really we have to do the same thing as for include-dirs,
relativise the paths into the current working directory and maintain any
extra libraries the user has specified.
Now the relevant section of the rts.conf file looks like:
```
library-dirs:
${pkgroot}/../rts/build
${pkgroot}/../../..//_build/stage1/rts/build
/nix/store/av4c0fib4rkmb6sa1074z0rb1ciria5b-gperftools-2.10/lib
/nix/store/2infxahfp9lj084xn3q9ib5ajks8447i-libffi-3.4.4/lib
library-dirs-static:
${pkgroot}/../rts/build
${pkgroot}/../../..//_build/stage1/rts/build
/nix/store/av4c0fib4rkmb6sa1074z0rb1ciria5b-gperftools-2.10/lib
/nix/store/2infxahfp9lj084xn3q9ib5ajks8447i-libffi-3.4.4/lib
dynamic-library-dirs:
${pkgroot}/../rts/build
${pkgroot}/../../..//_build/stage1/rts/build
/nix/store/av4c0fib4rkmb6sa1074z0rb1ciria5b-gperftools-2.10/lib
/nix/store/2infxahfp9lj084xn3q9ib5ajks8447i-libffi-3.4.4/lib
```

compiler: fix subword literal narrowing logic in the wasm NCG
This patch fixes the W8/W16 literal narrowing logic in the wasm NCG,
which used to lower it to something like i32.const -1, without
properly zeroing-out the unused higher bits. Fixes #22608.

compiler: fix lowering of CmmBlock in the wasm NCG
The CmmBlock datacon was not handled in lower_CmmLit, since I thought
it would have been eliminated after proc-point splitting. Turns out it
still occurs in very rare occasions, and this patch is needed to fix
T9329 for wasm.
