This commit fixes incorrectly built genapply when cross compiling
(#24347) by nuking all fragile CPP logic in it from the orbit. All
target-specific info are now read from DerivedConstants.h at runtime,
see added note for details. Also removes a legacy Makefile and adds
haskell language server support for genapply.

The wasm backend didn't properly make use of all Cmm global registers
due to #24347. Now that it is fixed, this patch re-enables full
register mapping for wasm32, and we can now generate smaller & faster
wasm modules that doesn't always spill arguments onto the stack. Fixes #22460 #24152.

We were emitting the wrong instructions for fused multiply-add
operations on LLVM:
- the instruction name is "llvm.fma.f32" or "llvm.fma.f64", not "fmadd"
- LLVM does not support other instructions such as "fmsub"; instead
we implement these by flipping signs of some arguments
- the instruction is an LLVM intrinsic, which requires handling it
like a normal function call instead of a machine instruction

A test *сс018* is attached (not sure about the naming convention though).
Note that without the fix, the test fails with the *dodgy-foreign-imports*
warning passed to stderr. The warning disappears after the fix.
GHC shouldn't warn on imports of natural function pointers from C by value
(which is feasible with CApiFFI), such as
```haskell
foreign import capi "cc018.h value f" f :: FunPtr (Int -> IO ())
```
where
```c
void (*f)(int);
```
See a related real-world use-case
[here](https://gitlab.com/daniel-casanueva/pcre-light/-/merge_requests/17).
There, GHC warns on import of C function pointer `pcre_free`.

In hand-written Cmm it can sometimes be necessary to atomically load
from memory deep within an expression (e.g. see the `CHECK_GC` macro).
This MachOp provides a convenient way to do so without breaking the
expression into multiple statements.

This commit enables the generic cmm optimizations in other NCGs to be
run in the wasm backend as well, followed by a late cmm control-flow
optimization pass. The added optimizations do catch some corner cases
not handled by the pre-NCG cmm pipeline and are useful in generating
smaller CFGs.

New syntax for WARNING and DEPRECATED pragmas was added,
namely namespace specifierss:
namespace_spec ::= 'type' | 'data' | {- empty -}
warning ::= warning_category namespace_spec namelist strings
deprecation ::= namespace_spec namelist strings
A new data type was introduced to represent these namespace specifiers:
data NamespaceSpecifier =
NoSpecifier |
TypeNamespaceSpecifier (EpToken "type") |
DataNamespaceSpecifier (EpToken "data")
Extension field XWarning now contains this NamespaceSpecifier.
lookupBindGroupOcc function was changed: it now takes NamespaceSpecifier
and checks that the namespace of the found names matches the passed flag.
With this change {-# WARNING data D "..." #-} pragma will only affect value
namespace and {-# WARNING type D "..." #-} will only affect type
namespace. The same logic is applicable to DEPRECATED pragmas.
Finding duplicated warnings inside rnSrcWarnDecls now takes into
consideration NamespaceSpecifier flag to allow warnings with the
same names that refer to different namespaces.

...mostly so that 16d6b7e835ffdcf9b894e79f933dd52348dedd0c
(which reworks unaligned writes in Builder) and the stuff in
https://github.com/haskell/bytestring/pull/631 can see wider testing.
The less-terrible code for unaligned writes used in Builder on
hosts not known to be ulaigned-friendly also takes less effort
for GHC to compile, resulting in a metric decrease for T21839c
on some platforms.
The metric increase on T21839r is caused by the unrelated commit
750dac33465e7b59100698a330b44de7049a345c. It perhaps warrants
further analysis and discussion (see #23822) but is not critical.

- Fixes #18324 #20020 #23147 #22788 #15598 #22086 #21206
- The change is detailed in
- Note [Expanding HsDo with HsExpansion] in `GHC.Tc.Gen.Do`
- Note [Doing HsExpansion in the Renamer vs Typechecker] in `GHC.Rename.Expr`
expains the rational of doing expansions in type checker as opposed to in the renamer
- Adds new datatypes:
- `GHC.Hs.Expr.XXExprGhcRn`: new datatype makes this expansion work easier
1. Expansion bits for Expressions, Statements and Patterns in (`ExpandedThingRn`)
2. `PopErrCtxt` a special GhcRn Phase only artifcat to pop the previous error message in the error context stack
- `GHC.Basic.Origin` now tracks the reason for expansion in case of Generated
This is useful for type checking cf. `GHC.Tc.Gen.Expr.tcExpr` case for `HsLam`
- Kills `HsExpansion` and `HsExpanded` as we have inlined them in `XXExprGhcRn` and `XXExprGhcTc`
- Ensures warnings such as
1. Pattern match checks
2. Failable patterns
3. non-() return in body statements are preserved
- Kill `HsMatchCtxt` in favor of `TcMatchAltChecker`
- Testcases:
* T18324 T20020 T23147 T22788 T15598 T22086
* T23147b (error message check),
* DoubleMatch (match inside a match for pmc check)
* pattern-fails (check pattern match with non-refutable pattern, eg. newtype)
* Simple-rec (rec statements inside do statment)
* T22788 (code snippet from #22788)
* DoExpanion1 (Error messages for body statments)
* DoExpansion2 (Error messages for bind statements)
* DoExpansion3 (Error messages for let statements)
Also repoint haddock to the right submodule so that the test (haddockHypsrcTest) pass
Metric Increase 'compile_time/bytes allocated':
T9020
The testcase is a pathalogical example of a `do`-block with many statements that do nothing.
Given that we are expanding the statements into function binds, we will have to bear
a (small) 2% cost upfront in the compiler to unroll the statements.

This patch is a preparation for @a-binders implementation. The main changes are:
* Skolemisation is now prepared to deal with @binders.
See Note [Skolemisation overview] in GHC.Tc.Utils.Unify.
Most of the action is in
- Utils.Unify.matchExpectedFunTys
- Gen.Pat.tcMatchPats
- Gen.Expr.tcPolyExprCheck
- Gen.Binds.tcPolyCheck
Some accompanying refactoring:
* I found that funTyConAppTy_maybe was doing a lot of allocation, and
rejigged userTypeError_maybe to avoid calling it.

This fixes a bug in 8db8d2fd1c881032b1b360c032b6d9d072c11723, where we could lose
track of acyclic components at the start of an unresolved cycle. We now ensure we
never loose track of any of these components.
As T24275 demonstrates, a "cyclic" SCC might not really be a true SCC:
When viewed without boot files, we have a single SCC
```
[REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A [main:T24275A {-# SOURCE #-}]]
```
But with boot files this turns into
```
[NONREC main:T24275B {-# SOURCE #-} [],
REC main:T24275B [main:T24275B {-# SOURCE #-},
main:T24275A {-# SOURCE #-}]
main:T24275A {-# SOURCE #-} [main:T24275B],
NONREC main:T24275A [main:T24275A {-# SOURCE #-}]]
```
Note that this is truly not an SCC, as no nodes are reachable from T24275B.hs-boot.
However, we treat this entire group as a single "SCC" because it seems so when we
analyse the graph without taking boot files into account.
Indeed, we must return a single ResolvedCycle element in the BuildPlan for this
as described in Note [Upsweep].
However, since after resolving this is not a true SCC anymore, `findCycle` fails
to find a cycle and we have a sub-optimal error message as a result.
To handle this, I extended `findCycle` to not assume its input is an SCC, and to
try harder to find cycles in its input.

In b521354216f2821e00d75f088d74081d8b236810 the testsuite gained the
capability to collect generic metrics. But this assumed that the test
was not linking and producing artifacts and we only wanted to track
object files, interface files, or build artifacts from the compiler
build. However, some backends, such as the JS backend, produce artifacts when
compiling, such as the jsexe directory which we want to track.
This patch:
- tweaks the testsuite to collect generic metrics on any build artifact
in the test directory.
- expands the exe_extension function to consider windows and adds the
ignore_extension flag.
- Modifies certain tests to add the ignore_extension flag. Tests such as
heaprof002 expect a .ps file, but on windows without ignore_extensions
the testsuite will look for foo.exe.ps. Hence the flag.
- adds the size_hello_artifact test

This logic appears to be incorrect as it would drop any dependency which
was not in a direct dependency of the package being linked.
In the ghc-internals split this started to cause errors because
`ghc-internal` is not a direct dependency of most packages, and hence
important symbols to keep which are hard coded into the js runtime were
getting dropped.

Here we move a good deal of the implementation of `base` into a new
package, `ghc-internal` such that it can be evolved independently
from the user-visible interfaces of `base`.
While we want to isolate implementation from interfaces, naturally, we
would like to avoid turning `base` into a mere set of module re-exports.
However, this is a non-trivial undertaking for a variety of reasons:
* `base` contains numerous known-key and wired-in things, requiring
corresponding changes in the compiler
* `base` contains a significant amount of C code and corresponding
autoconf logic, which is very fragile and difficult to break apart
* `base` has numerous import cycles, which are currently dealt with via
carefully balanced `hs-boot` files
* We must not break existing users
To accomplish this migration, I tried the following approaches:
* [Split-GHC.Base]: Break apart the GHC.Base knot to allow incremental
migration of modules into ghc-internal: this knot is simply too
intertwined to be easily pulled apart, especially given the rather
tricky import cycles that it contains)
* [Move-Core]: Moving the "core" connected component of base (roughly
150 modules) into ghc-internal. While the Haskell side of this seems
tractable, the C dependencies are very subtle to break apart.
* [Move-Incrementally]:
1. Move all of base into ghc-internal
2. Examine the module structure and begin moving obvious modules (e.g.
leaves of the import graph) back into base
3. Examine the modules remaining in ghc-internal, refactor as necessary
to facilitate further moves
4. Go to (2) iterate until the cost/benefit of further moves is
insufficient to justify continuing
5. Rename the modules moved into ghc-internal to ensure that they don't
overlap with those in base
6. For each module moved into ghc-internal, add a shim module to base
with the declarations which should be exposed and any requisite
Haddocks (thus guaranteeing that base will be insulated from changes
in the export lists of modules in ghc-internal
Here I am using the [Move-Incrementally] approach, which is empirically
the least painful of the unpleasant options above

There are situations where LLVM will produce assembly which older gcc

produces assembly which the default gcc doesn't support.
A more robust solution in the long term is to require a specific LLVM
compatible assembler when using -fllvm.

Per #23966, I want the top-level configure to only generate
configuration data for Hadrian, not do any "real" tasks on its own.
This is part of that effort --- one less file generated by it.
(It is still done with a `.in` file, so in a future world non-Hadrian
also can easily create this file.)
Split modules:
- GHC.CmmToLlvm.Config
- GHC.CmmToLlvm.Version
- GHC.CmmToLlvm.Version.Bounds
- GHC.CmmToLlvm.Version.Type
This also means we can get rid of the silly `unused.h` introduced in
!6803 / 7dfcab2f4bcb7206174ea48857df1883d05e97a2 as temporary kludge.

The eras profiling mode is useful for tracking the life-time of
closures. When a closure is written, the current era is recorded in the
profiling header. This records the era in which the closure was created.
* Enable with -he
* User mode: Use functions ghc-experimental module GHC.Profiling.Eras to modify the era
* Automatically: --automatic-era-increment, increases the user era on major
collections
* The first era is era 1
* -he<era> can be used with other profiling modes to select a specific
era
If you just want to record the era but not to perform heap profiling you
can use `-he --no-automatic-heap-samples`.

Some Haskell codes unsafely cast StablePtr into ptr to compare against
NULL. E.g. in direct-sqlite:
if castStablePtrToPtr aggStPtr /= nullPtr then
where `aggStPtr` is read (`peek`) from zeroed memory initially.
We fix this by giving these StablePtr the same representation as other
null pointers. It's safe because StablePtr at offset 0 is unused (for
this exact reason).

Support linking C sources with JS output of the JavaScript backend.
See the added documentation in the users guide.
The implementation simply extends the JS linker to use the objects (.o)
that were already produced by the emcc compiler and which were filtered
out previously. I've also added some options to control the link with C
functions (see the documentation about pragmas).
With this change I've successfully compiled the direct-sqlite package
which embeds the sqlite.c database code. Some wrappers are still
required (see the documentation about wrappers) but everything generic
enough to be reused for other libraries have been integrated into
rts/js/mem.js.

emcc would sometime output messages like:
cache:INFO: generating system asset: symbol_lists/424b44514e43d789148e69e4e7d1c7fdc0350b79.json... (this will be cached in "/emsdk/upstream/emscripten/cache/symbol_lists/424b44514e43d789148e69e4e7d1c7fdc0350b79.json" for subsequent builds)
cache:INFO: - ok
Cf https://github.com/emscripten-core/emscripten/issues/18607
This breaks our tests matching the stderr output. We avoid this by setting EMCC_LOGGING=0

Add support for heap profiling while using the nonmoving collector.
We greatly simply the implementation by disabling concurrent collection for
GCs when heap profiling is enabled. This entails that the marked objects on
the nonmoving heap are exactly the live objects.
Note that we match the behaviour for live bytes accounting by taking the size
of objects on the nonmoving heap to be that of the segment's block
rather than the object itself.
