Hadrian: correctly detect AR at-file support
Stage0's ar may not support at-files. Take it into account.
Found while cross-compiling from Darwin to Windows.

ci: Disable HLint job due to excessive runtime
The HLint jobs takes much longer to run (20 minutes) after "Give the RTS it's own configure script" eb5a6b91
Now the CI job will build the stage0 compiler before it generates the necessary RTS headers.
We either need to:
* Fix the linting rules so they take much less time
* Revert the commit
* Remove the linting of base from the hlint job
* Remove the hlint job
This is highest priority as it is affecting all CI pipelines.
For now I am just disabling the job because there are many more pressing
matters at hand.

Store dehydrated data structures in CgModBreaks
This fixes a tricky leak in GHCi where we were retaining old copies of
HscEnvs when reloading. If not all modules were recompiled then these
hydrated fields in break points would retain a reference to the old
HscEnv which could double memory usage.

Force more in NFData Name instance
Doesn't force the lazy `OccName` field (#19619) which is already known
as a really bad source of leaks.
When we slam the hammer storing Names on disk (in interface files or the
like), all this should be forced as otherwise a `Name` can easily retain
an `Id` and hence the entire world.

This occname has just been derived from an `Id`, so need to force it
promptly so we can release the Id back to the world.
Another symptom of the bug caused by #19619

Replace errors from badOrigBinding with new one (#22839)
Problem: in 02279a9c the type-level [] syntax was changed from a built-in name
to an alias for the GHC.Types.List constructor. badOrigBinding assumes that if
a name is not built-in then it must have come from TH quotation, but this is
not necessarily the case with [].
The outdated assumption in badOrigBinding leads to incorrect error messages.
This code:
data []
Fails with "Cannot redefine a Name retrieved by a Template Haskell quote: []"
Unfortunately, there is not enough information in RdrName to directly determine
if the name was constructed via TH or by the parser, so this patch changes the
error message instead.
It unifies TcRnIllegalBindingOfBuiltIn and TcRnNameByTemplateHaskellQuote
into a new error TcRnBindingOfExistingName and changes its wording to avoid
guessing the origin of the name.

This reverts commit d0d7ba0fb053ebe7f919a5932066fbc776301ccd.
The module now lacks a dependency on GHC.Num.BigNat which it implicitly
depends on. It is causing all CI jobs to fail so we revert without haste
whilst the patch can be fixed.

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

Previously UnliftedTVar2 would fail when run with multiple capabilities

Also, refactor the the executable to now succeed with no output and
fails with an exit code.

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.

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

Adjust the pattern-match checker for Or patterns
Previously, any pattern match or guard could be desugared into a vector of
elementary `PmGrd`s (called `GrdVec`) that must all match conjunctively.
But with Or patterns, that is bound to change, quite drastically so:
Or patterns imply disjunctive matching, and because they may occur
nestedly inside other patterns, we need to widen our `GrdVec` type
to accomodate both conjunctive/sequential as well as disjunctive/alternative
composition.
This leads to a rather modest generalisation of the guard tree formalism,
yielding guard *directed acyclic graphs*. These DAGs are *series-parallel*,
that is to say a *very* benign kind of DAG that is nearly a tree, and which
can be defined easily as an inductive data type, `GrdDag`.
Beyond adjustments to use the new graph constructors, the rest is just routine
re-use of the existing `topToBottom` combinator in `GHC.HsToCore.Pmc.Check`.
Nice!
