testsuite: increase timeout of ghc-api tests for wasm32
ghc-api tests for wasm32 are more likely to timeout due to the large
wasm module sizes, especially when testing with wasm native tail
calls, given wasmtime's handling of tail call opcodes are suboptimal
at the moment. It makes sense to increase timeout specifically for
these tests on wasm32. This doesn't affect other targets, and for
wasm32 we don't increase timeout for all tests, so not to risk letting
major performance regressions slip through the testsuite.

Modularity: modularize external linker
Decouple runLink from DynFlags to allow calling runLink more easily.
This is preliminary work for calling Emscripten's linker (emcc) from
our JavaScript linker.

Fix a bug in tail calls with ticks
See #24078 for the diagnosis. The change affects only
the Tick case of occurrence analysis.
It's a bit hard to test, so no regression test (yet anyway).

[PEi386] Mask SYM_TYPE_DUP_DISCARD in makeSymbolExtra
48e391952c17ff7eab10b0b1456e3f2a2af28a9b
introduced `SYM_TYPE_DUP_DISCARD` to the bitfield.
The linker however, failed to mask the `SYM_TYPE_DUP_DISCARD` value.
Thus `== SYM_TYPE_CODE` comparisons easily failed. This lead to us
relocating DATA lookups (GOT) into E8 (call) and E9 (jump) instructions.

docs: fix ScopedTypeVariables example (#24101)
The previous example didn't compile.
Furthermore, it wasn't demonstrating the point properly.
I have changed it to an example which shows that 'a' in the signature

More robust checking for DataKinds
As observed in #22141, GHC was not doing its due diligence in catching code
that should require `DataKinds` in order to use. Most notably, it was allowing
the use of arbitrary data types in kind contexts without `DataKinds`, e.g.,
```hs
data Vector :: Nat -> Type -> Type where
```
This patch revamps how GHC tracks `DataKinds`. The full specification is
written out in the `DataKinds` section of the GHC User's Guide, and the
implementation thereof is described in `Note [Checking for DataKinds]` in
`GHC.Tc.Validity`. In brief:
* We catch _type_-level `DataKinds` violations in the renamer. See
`checkDataKinds` in `GHC.Rename.HsType` and `check_data_kinds` in
`GHC.Rename.Pat`.
* We catch _kind_-level `DataKinds` violations in the typechecker, as this
allows us to catch things that appear beneath type synonyms. (We do *not*
want to do this in type-level contexts, as it is perfectly fine for a type
synonym to mention something that requires DataKinds while still using the
type synonym in a module that doesn't enable DataKinds.) See `checkValidType`
in `GHC.Tc.Validity`.
* There is now a single `TcRnDataKindsError` that classifies all manner of
`DataKinds` violations, both in the renamer and the typechecker. The
`NoDataKindsDC` error has been removed, as it has been subsumed by
`TcRnDataKindsError`.
* I have added `CONSTRAINT` is `isKindTyCon`, which is what checks for illicit
uses of data types at the kind level without `DataKinds`. Previously,
`isKindTyCon` checked for `Constraint` but not `CONSTRAINT`. This is
inconsistent, given that both `Type` and `TYPE` were checked by `isKindTyCon`.
Moreover, it thwarted the implementation of the `DataKinds` check in
`checkValidType`, since we would expand `Constraint` (which was OK without
`DataKinds`) to `CONSTRAINT` (which was _not_ OK without `DataKinds`) and
reject it. Now both are allowed.
* I have added a flurry of additional test cases that test various corners of
`DataKinds` checking.
Fixes #22141.

EPA: Use full range for Anchor
This change requires a series of related changes, which must all land
at the same time, otherwise all the EPA tests break.
* Use the current Anchor end as prior end
Use the original anchor location end as the source of truth for
calculating print deltas.
This allows original spacing to apply in most cases, only changed
AST items need initial delta positions.
* Add DArrow to TrailingAnn
* EPA Introduce HasTrailing in ExactPrint
Use [TrailingAnn] in enterAnn and remove it from
ExactPrint (LocatedN RdrName)
* In HsDo, put TrailingAnns at top of LastStmt
* EPA: do not convert comments to deltas when balancing.
* EPA: deal with fallout from getMonoBind
* EPA fix captureLineSpacing
* EPA print any comments in the span before exiting it
* EPA: Add comments to AnchorOperation
* EPA: remove AnnEofComment, it is no longer used

This fixes several compatability issues when using 9.8.1 as the boot

* An incorrect version guard on the stack decoding logic in ghc-heap

* ghc is no longer wired in, so we have to remove the -this-unit-id ghc
call.

Add NCG support for common 64bit operations to the x86 backend.
These used to be implemented via C calls which was obviously quite bad

T2T in Expressions (#23738)
This patch implements the T2T (term-to-type) transformation in
expressions. Given a function with a required type argument
vfun :: forall a -> ...
the user can now call it as
vfun (Maybe Int)
instead of
vfun (type (Maybe Int))
The Maybe Int argument is parsed and renamed as a term (HsExpr), but then
undergoes a conversion to a type (HsType).
See the new function expr_to_type in compiler/GHC/Tc/Gen/App.hs
and Note [RequiredTypeArguments and the T2T mapping]
Left as future work: checking for puns.

Add a test for I/O managers
It tries to cover the cases of multiple threads waiting on the same
fd for reading and multiple threads waiting for writing, including
wait cancellation by async exceptions.
It should work for any I/O manager, in-RTS or in-Haskell.
Unfortunately it will not currently work for Windows because it relies
on anonymous unix sockets. It could in principle be ported to use
Windows named pipes.
