Restore mingwex dependency on Windows
This partially reverts some of the changes in !9475 to make `base` and
`ghc-prim` depend on the `mingwex` library on Windows. It also restores the
RTS's stubs for `mingwex`-specific symbols such as `_lock_file`.
This is done because the C runtime provides `libmingwex` nowadays, and
moreoever, not linking against `mingwex` requires downstream users to link
against it explicitly in difficult-to-predict circumstances. Better to always
link against `mingwex` and prevent users from having to do the guesswork
themselves.
See https://gitlab.haskell.org/ghc/ghc/-/merge_requests/10360#note_495873 for
the discussion that led to this.

RtsSymbols.c: Remove mingwex symbol stubs
As of !9475, the RTS now links against `ucrt` instead of `msvcrt` on Windows,
which means that the RTS no longer needs to declare stubs for the `__mingw_*`
family of symbols. Let's remove these stubs to avoid confusion.
Fixes #23309.

Consistently use validity checks for TH conversion of data constructors
We were checking that TH-spliced data declarations do not look like this:
```hs
data D :: Type = MkD Int
```
But we were only doing so for `data` declarations' data constructors, not for
`newtype`s, `data instance`s, or `newtype instance`s. This patch factors out
the necessary validity checks into its own `cvtDataDefnCons` function and uses
it in all of the places where it needs to be.
Fixes #22559.

Fix behaviour of -keep-tmp-files when used in OPTIONS_GHC pragma
This fixes the behaviour of -keep-tmp-files when used in an OPTIONS_GHC
pragma for files with module level scope.
Instead of simple not deleting the files, we also need to remove them
from the TmpFs so they are not deleted later on when all the other files
are deleted.
There are additional complications because you also need to remove the
directory where these files live from the TmpFs so we don't try to
delete those later either.
I added two tests.
1. Tests simply that -keep-tmp-files works at all with a single module
and --make mode.
2. The other tests that temporary files are deleted for other modules
which don't enable -keep-tmp-files.
Fixes #23339

withDeferredDiagnostics: When debugIsOn, write landmine into IORef to catch use-after-free.
Ticket #23305 reports an error where we were attempting to use the
logger which was created by withDeferredDiagnostics after its scope had
ended.
This problem would have been caught by this patch and a validate build:
```
+*** Exception: Use after free
+CallStack (from HasCallStack):
+ error, called at compiler/GHC/Driver/Make.hs:<line>:<column> in <package-id>:GHC.Driver.Make
```
This general issue is tracked by #20981

Don't return complete HscEnv from upsweep
By returning a complete HscEnv from upsweep the logger (as introduced by
withDeferredDiagnostics) was escaping the scope of
withDeferredDiagnostics and hence we were losing error messages.
This is reminiscent of #20981, which also talks about writing errors
into messages after their scope has ended.
See #23305 for details.

Dump `SpecConstr` specialisations separately
Introduce a `-ddump-spec-constr` flag which debugs specialisations from
`SpecConstr`. These are no longer shown when you use `-ddump-spec`.

Fixes #18324 #23147
Expands do notation before typechecking using `HsExpansion`
- Adds testcases T18324, T18324b, DoubleMatch
Expands
- Do statements
- Monadic do statements
- monadic fix blocks
- make sure fail is used for pattern match failures in bind statments
- Makes sure unused binds generate warnings
- runs the pattern match check in generated lambda exprs to avoid getting suprious pattern match failures. c.f. pmcheck/should_compile/DoubleMatch.hs
- PopSrcSpan in HsExpr to pop error context
- Discards default monad fail alternatives that are spuriously generated
- Make sure we check for generated loc span for checking if the (>>) is user written or expanded for /do/ purposes
- - - - -
66f81425 by Apoorv Ingle at 2023-06-09T15:48:46-05:00
- Add PopSrcSpan (XXExprGhcRn) in appropriate places while expanding statements
- correct source spans displayed for warnDiscardedDoBindings
- use `mkExpandStmt` to store original stmts along with expanded expr for using the right context for error message printing
- improves error messages for applicative do
- remove special case from isMatchContextPmChecked (long distance info is now properly propogated)
- set correct src spans to statement expansions
- Match ctxt while type checking HsLam is different if the lambda match is due to an expression generated from a do block
- call tcExpr and not tcApp in PopSrcSpan so make sure impredicativity works fine
- look into XExprs in tcInferAppHead_maybe for infering the type to make T18324 typecheck and run

a861f273 by Apoorv Ingle at 2023-06-09T15:48:46-05:00
- don't add any ctxt in addExprCtxt for `XExpr(ExpandedStmt{})` as it is not very useful, the statement ctxt is already added by `tcExpr` and `addHeadCtxt`
