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.

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.

Instead of sprinkling the codebase with

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.

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.

-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.

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)

Fire RULES in the Specialiser
The Specialiser has, for some time, fires class-op RULES in the
specialiser itself: see
Note [Specialisation modulo dictionary selectors]
This MR beefs it up a bit, so that it fires /all/ RULES in the
specialiser, not just class-op rules. See
Note [Fire rules in the specialiser]
The result is a bit more specialisation; see test
simplCore/should_compile/T21851_2
This pushed me into a bit of refactoring. I made a new data types
GHC.Core.Rules.RuleEnv, which combines
- the several source of rules (local, home-package, external)
- the orphan-module dependencies
in a single record for `getRules` to consult. That drove a bunch of
follow-on refactoring, including allowing me to remove
cr_visible_orphan_mods from the CoreReader data type.
I moved some of the RuleBase/RuleEnv stuff into GHC.Core.Rule.
The reorganisation in the Simplifier improve compile times a bit
(geom mean -0.1%), but T9961 is an outlier

Make indexError work better
The problem here is described at some length in
Note [Boxity for bottoming functions] and
Note [Reboxed crud for bottoming calls] in GHC.Core.Opt.DmdAnal.

makes it much less vulnerable to the problem described in
these Notes.
(This came up in another line of work, where a small change made

hadrian: add targetSupportsThreadedRts flag
This patch adds a targetSupportsThreadedRts flag to indicate whether
the target supports the threaded rts at all, different from existing
targetSupportsSMP that checks whether -N is supported by the RTS. All
existing flavours have also been updated accordingly to respect this
flags.
Some targets (e.g. wasm32-wasi) does not support the threaded rts,
therefore this flag is needed for the default flavours to work. It
makes more sense to have proper autoconf logic to check for threading
support, but for the time being, we just set the flag to False iff the
target is wasm32.

add the two key graph modules from Martin Erwig's FGL
Martin Erwig's FGL (Functional Graph Library) provides an "inductive"
representation of graphs. A general graph has labeled nodes and
labeled edges. The key operation on a graph is to decompose it by
removing one node, together with the edges that connect the node to
the rest of the graph. There is also an inverse composition
operation.
The decomposition and composition operations make this representation
of graphs exceptionally well suited to implement graph algorithms in
which the graph is continually changing, as alluded to in #21259.
This commit adds `GHC.Data.Graph.Inductive.Graph`, which defines the
interface, and `GHC.Data.Graph.Inductive.PatriciaTree`, which provides
an implementation. Both modules are taken from `fgl-5.7.0.3` on
Hackage, with these changes:
- Copyright and license text have been copied into the files
themselves, not stored separately.
- Some calls to `error` have been replaced with calls to `panic`.
- Conditional-compilation support for older versions of GHC,
`containers`, and `base` has been removed.

rts: workaround cmm's improper variadic ccall breaking wasm32 typechecking
Unlike other targets, wasm requires the function signature of the call
site and callee to strictly match. So in Cmm, when we call a C
function that actually returns a value, we need to add an _unused
local variable to receive it, otherwise type error awaits.
An even bigger problem is calling variadic functions like barf() and
such. Cmm doesn't support CAPI calling convention yet, so calls to
variadic functions just happen to work in some cases with some
target's ABI. But again, it doesn't work with wasm. Fortunately, the
wasm C ABI lowers varargs to a stack pointer argument, and it can be
passed NULL when no other arguments are expected to be passed. So we
also add the additional unused NULL arguments to those functions, so
to fix wasm, while not affecting behavior on other targets.

rts: prefer ffi_type_void over FFI_TYPE_VOID
This patch uses ffi_type_void instead of FFI_TYPE_VOID in the
interpreter code, since the FFI_TYPE_* macros are not available in
libffi-wasm32 yet. The libffi public documentation also only mentions
the lower-case ffi_type_* symbols, so we should prefer the lower-case
API here.

rts: don't define RTS_USER_SIGNALS when signal.h is not present
In the rts, we have a RTS_USER_SIGNALS macro, and most signal-related
logic is guarded with RTS_USER_SIGNALS. This patch extends the range
of code guarded with RTS_USER_SIGNALS, and define RTS_USER_SIGNALS iff
signal.h is actually detected by autoconf. This is required for
wasm32-wasi to work, which lacks signals.

rts: use HAVE_GETPID to guard subprocess related logic
We've previously added detection of getpid() in autoconf. This patch
uses HAVE_GETPID to guard some subprocess related logic in the RTS.
This is required for certain targets like wasm32-wasi, where there
isn't a process model at all.

rts: RtsStartup: chdir to PWD on wasm32
This patch adds a wasm32-specific behavior to RtsStartup logic. When
the PWD environment variable is present, we chdir() to it first.
The point is to workaround an issue in wasi-libc: it's currently not
possible to specify the initial working directory, it always defaults
to / (in the virtual filesystem mapped from some host directory). For
some use cases this is sufficient, but there are some other cases
(e.g. in the testsuite) where the program needs to access files

rts: no timer for wasm32
Due to the lack of threads, on wasm32 there can't be a background
timer that periodically resets the context switch flag. This patch
disables timer for wasm32, and also makes the scheduler default to -C0
on wasm32 to avoid starving threads.

rts: RtsSymbols: empty RTS_POSIX_ONLY_SYMBOLS for wasm32
The default RTS_POSIX_ONLY_SYMBOLS doesn't make sense on wasm32.

rts: Schedule: no FORKPROCESS_PRIMOP_SUPPORTED on wasm32
On wasm32 there isn't a process model at all, so no
FORKPROCESS_PRIMOP_SUPPORTED.

rts: LibffiAdjustor: adapt to ffi_alloc_prep_closure interface for wasm32
libffi-wasm32 only supports non-standard libffi closure api via
ffi_alloc_prep_closure(). This patch implements
ffi_alloc_prep_closure() via standard libffi closure api on other
targets, and uses it to implement adjustor functionality.

rts: don't return memory to OS on wasm32
This patch makes the storage manager not return any memory on wasm32.
The detailed reason is described in Note [Megablock allocator on
wasm].

rts: make flushExec a no-op on wasm32
This patch makes flushExec a no-op on wasm32, since there's no such
thing as executable memory on wasm32 in the first place.

rts: RtsStartup: don't call resetTerminalSettings, freeThreadingResources on wasm32
This patch prevents resetTerminalSettings and freeThreadingResources
to be called on wasm32, since there is no TTY or threading on wasm32
at all.

rts: OSThreads.h: stub types for wasm32
This patch defines stub Condition/Mutex/OSThreadId/ThreadLocalKey
types for wasm32, just enough to unblock compiling RTS. Any
threading-related functionality has been patched to be disabled on
wasm32.

base: fall back to using monotonic clock to emulate cputime on wasm32
On wasm32, we have to fall back to using monotonic clock to emulate
cputime, since there's no native support for cputime as a clock id.

base: more autoconf checks for wasm32
This patch adds more autoconf checks to base, since those functions
and headers may exist on other POSIX systems but don't exist on
wasm32.

compiler: add util functions for UniqFM and UniqMap
This patch adds addToUFM_L (backed by insertLookupWithKey),
addToUniqMap_L and intersectUniqMap_C. These UniqFM/UniqMap util
functions are used by the wasm32 NCG.

driver: avoid -Wl,--no-as-needed for wasm32
The driver used to pass -Wl,--no-as-needed for LLD linking. This is
actually only supported for ELF targets, and must be avoided when
linking for wasm32.

compiler: allow big arith for wasm32
This patch enables Cmm big arithmetic on wasm32, since 64-bit
arithmetic can be efficiently lowered to wasm32 opcodes.

otherwise the switch tables we generate may exceed the br_table
maximum allowed size.

compiler: annotate CmmFileEmbed with blob length
This patch adds the blob length field to CmmFileEmbed. The wasm32 NCG
needs to know the precise size of each data segment.

ci: add a stronger test for cross bindists
This commit adds a simple GHC API program that parses and reprints the
original hello world program used for basic testing of cross bindists.
Before there's full cross-compilation support in the test suite
driver, this provides better coverage than the original test.
