rts: `name` argument of `createOSThread` can be `const`
Since we don't intend to ever change the incoming string, declare this
to be true.
Also, in the POSIX implementation, the argument is no longer `STG_UNUSED`
(since ee0deb8054da2a597fc5624469b4c44fd769ada2) in any code path.
See: https://gitlab.haskell.org/ghc/ghc/-/commit/ee0deb8054da2a597fc5624469b4c44fd769ada2#note_460080

rts: fix lifetime of `start_thread`s `name` value
Since, unlike the code in ee0deb8054da2^, usage of the `name` value
passed to `createOSThread` now outlives said function's lifetime, and
could hence be released by the caller by the time the new thread runs
`start_thread`, it needs to be copied.

rts: fix OS thread naming in ticker
Since ee0deb805, the use of `pthread_setname_np` on Darwin was fixed
when invoking `createOSThread`. However, the 'ticker' has some
thread-creation code which doesn't rely on `createOSThread`, yet also
uses `pthread_setname_np`.
This patch enforces all thread creation to go through a single
function, which uses the (correct) thread-naming code introduced in
ee0deb805.

ThToHs: fix overzealous parenthesization
Before this patch, when converting from TH.Exp to LHsExpr GhcPs,
the compiler inserted more parentheses than required:
((f a) (b + c)) d
This was happening because the LHS of the function application was
parenthesized as if it was the RHS.
Now we use funPrec and appPrec appropriately and produce sensibly
parenthesized expressions:
f a (b + c) d
I also took the opportunity to remove the special case for LamE,
which was not special at all and simply duplicated code.

Add accurate skolem info when quantifying
Ticket #22379 revealed that skolemiseQuantifiedTyVar was
dropping the passed-in skol_info on the floor when it encountered
a SkolemTv. Bad! Several TyCons thereby share a single SkolemInfo
on their binders, which lead to bogus error reports.

rts: introduce (and use) `STG_NORETURN`
Instead of sprinkling the codebase with
`GNU(C3)_ATTRIBUTE(__noreturn__)`, add a `STG_NORETURN` macro (for,
basically, the same thing) similar to `STG_UNUSED` and others, and
update the code to use this macro where applicable.

rts: specify deallocator of allocating functions
This patch adds a new `STG_MALLOC1` macro (and its counterpart
`STG_MALLOC2` for completeness) which allows to specify the deallocation
function to be used with allocations of allocating functions, and
applies it to `stg*allocBytes`.
It also fixes a case where `free` was used to free up an
`stgMallocBytes` allocation, found by the above change.

gen-dll: Drop it
Currently it is only used by the make build system, which is soon to be
retired, and it has not built since 41cf758b. We may need to reintroduce
it when dynamic-linking support is introduced on Windows, but we will
cross that bridge once we get there.
Fixes #21753.

Port foundation numeric tests to GHC testsuite
This commit ports the numeric tests which found a regression in GHC-9.4.
https://github.com/haskell-foundation/foundation/issues/571
Included in the commit is a simple random number generator and
simplified QuickCheck implementation. In future these could be factored
out of this standalone file and reused as a general purpose library
which could be used for other QuickCheck style tests in the testsuite.
See #22282

Clarify status of bindings in WholeCoreBindings
Gergo points out that these bindings are tidied, rather than prepd as
the variable claims. Therefore we update the name of the variable to

future confusion.

CI: Allow hadrian-ghc-in-ghci to run in nightlies

Bump unix submodule to 2.8.0.0
Also bumps process and ghc-boot bounds on unix.
For hadrian, when cross-compiling, we add -Wwarn=unused-imports
-Wwarn=unused-top-binds to validation flavour. Further fixes in unix
and/or hsc2hs is needed to make it completely free of warnings; for
the time being, this change is needed to unblock other
cross-compilation related work.

Define `Infinite` list and use where appropriate.
Also add perf test for infinite list fusion.
In particular, in `GHC.Core`, often we deal with infinite lists of roles. Also in a few locations we deal with infinite lists of names.
Thanks to simonpj for helping to write the Note [Fusion for `Infinite` lists].

Fix TypeData issues (fixes #22315 and #22332)
There were two bugs here:
1. Treating type-level constructors as PromotedDataCon doesn't always
work, in particular because constructors promoted via DataKinds are
called both T and 'T. (Tests T22332a, T22332b, T22315a, T22315b)
Fix: guard these cases with isDataKindsPromotedDataCon.
2. Type-level constructors were sent to the code generator, producing
things like constructor wrappers. (Tests T22332a, T22332b)
Fix: test for them in isDataTyCon.
Other changes:
* changed the marking of "type data" DataCon's as suggested by SPJ.
* added a test TDGADT for a type-level GADT.
* comment tweaks
* change tcIfaceTyCon to ignore IfaceTyConInfo, so that IfaceTyConInfo
is used only for pretty printing, not for typechecking. (SPJ)
