<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PmCheck: Handle ⊥ and strict fields correctly (#18341)
In #18341, we discovered an incorrect digression from Lower Your Guards.
This MR changes what's necessary to support properly fixing #18341.
In particular, bottomness constraints are now properly tracked in the
oracle/inhabitation testing, as an additional field
`vi_bot :: Maybe Bool` in `VarInfo`. That in turn allows us to
model newtypes as advertised in the Appendix of LYG and fix #17725.
Proper handling of ⊥ also fixes #17977 (once again) and fixes #18670.
For some reason I couldn't follow, this also fixes #18273.
I also added a couple of regression tests that were missing. Most of
them were already fixed before.
In summary, this patch fixes #18341, #17725, #18273, #17977 and #18670.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PmCheck: Disattach COMPLETE pragma lookup from TyCons
By not attaching COMPLETE pragmas with a particular TyCon and instead
assume that every COMPLETE pragma is applicable everywhere, we can
drastically simplify the logic that tries to initialise available
COMPLETE sets of a variable during the pattern-match checking process,
as well as fixing a few bugs.
Of course, we have to make sure not to report any of the
ill-typed/unrelated COMPLETE sets, which came up in a few regression
tests.
In doing so, we fix #17207, #18277 and #14422.
There was a metric decrease in #18478 by ~20%.

By taking and returning an `InertSet`.
Every new `TcS` session can then pick up where a prior session left with
`setTcSInerts`.
Since we don't want to unflatten the Givens (and because it leads to
infinite loops, see !3971), we introduced a new variant of `runTcS`,
`runTcSInerts`, that takes and returns the `InertSet` and makes
sure not to unflatten the Givens after running the `TcS` action.
Fixes #18645 and #17836.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Extract definition of DsM into GHC.HsToCore.Types
`DsM` was previously defined in `GHC.Tc.Types`, along with `TcM`. But
`GHC.Tc.Types` is in the set of transitive dependencies of `GHC.Parser`,
a set which we aim to minimise. Test case `CountParserDeps` checks for
that.
Having `DsM` in that set means the parser also depends on the innards of
the pattern-match checker in `GHC.HsToCore.PmCheck.Types`, which is the
reason we have that module in the first place.
In the previous commit, we represented the `TyState` by an `InertSet`,
but that pulls the constraint solver as well as 250 more modules into
the set of dependencies, triggering failure of `CountParserDeps`.
Clearly, we want to evolve the pattern-match checker (and the desugarer)
without being concerned by this test, so this patch includes a small
refactor that puts `DsM` into its own module.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Hackily decouple the parser from the desugarer
In a hopefully temporary hack, I re-used the idea from !1957 of using a
nullary type family to break the dependency from GHC.Driver.Hooks on the
definition of DsM ("Abstract Data").
This in turn broke the last dependency from the parser to the desugarer.
More details in `Note [The Decoupling Abstract Data Hack]`.
In the future, we hope to undo this hack again in favour of breaking the
dependency from the parser to DynFlags altogether.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Care with implicit-parameter superclasses
Two bugs, #18627 and #18649, had the same cause: we were not
account for the fact that a constaint tuple might hide an implicit
parameter.
The solution is not hard: look for implicit parameters in
superclasses. See Note [Local implicit parameters] in
GHC.Core.Predicate.
Then we use this new function in two places
* The "short-cut solver" in GHC.Tc.Solver.Interact.shortCutSolver
which simply didn't handle implicit parameters properly at all.
This fixes #18627
* The specialiser, which should not specialise on implicit parameters
This fixes #18649
There are some lingering worries (see Note [Local implicit
parameters]) but things are much better.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Parser.y: clarify treatment of @{-# UNPACK #-}
Before this patch, we had this parser production:
ftype : ...
| ftype PREFIX_AT tyarg { ... }
And 'tyarg' is defined as follows:
tyarg : atype { ... }
| unpackedness atype { ... }
So one might get the (false) impression that that parser production is
intended to parse things like:
F @{-# UNPACK #-} X
However, the lexer wouldn't produce PREFIX_AT followed by 'unpackedness',
as the '@' operator followed by '{-' is not considered prefix.
Thus there's no point using 'tyarg' after PREFIX_AT,
and a simple 'atype' will suffice:
ftype : ...
| ftype PREFIX_AT atype { ... }
This change has no user-facing consequences. It just makes the grammar a
bit more clear.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Implement ghc-debug API (#18405)
There are four components to this patch which make it possible to
implement `ghc-debug`.
1. Add four new functions to the RtsAPI.
* rts_pause and rts_unpause allow an external process to completely
pause and unpause the RTS.
* rts_listThreads and rts_listMiscRoots are used to find the current
roots of the garbage collector.
These changes also mean that `Task.h` is exposed to the user.
2. Generalise the `ghc-heap` API so that raw `Word`s can be returned
rather than actual objects. This is necessary when trying to decode
closures on an external process because the pointers in such closures
are correct for the internal rather than external process. If you used
the previous API then you would get a segfault as the garbage collector
would try to traverse into these nonsensical branches.
```
-- before
getClosureData :: a -> IO Closure
-- after
getClosureDataX :: (forall c . c -> IO (Ptr StgInfoTable, [Word], [b]))
-> a -> IO (GenClosure b)
```
For the normal case `b` is instantiated to `Box`, which contains a
pointer to a heap object.
```
data Box = Box a
-- GenClosure Box
```
For `ghc-debug` we instead just take the word of the address as we have
to explicitly interpret it on the external process.
```
GenClosure Word
```
3. Support for decoding `TSO` and `STACK` closures is partially
implemented. There is still quite a bit of work to do to finish both but
these at least allow us to make some more progress.
4. findPtr is generalised to take a callback argument. This means that
its result can be communicated to the debugger rather than just printing
out the result. The debugger has a function which invokes `findPtr` and
passes a callback which sends the result over a socket.

To assert - otherwise dynamic - properties, a new, non-running TSO is

size is renamed to stack_size to use a dedicated type.

These are the data structures used by profiling, i.e. they are only

results into `Nothing`.
To reduce unnecessary decoding, a state monad transformer is used to
provide caching for CostCentres.
Because the three types form a circular data structure, loop-breakers
are applied to prevent endless decoding loops.
