compiler: use zero cost coerce in hoopl setElems/mapToList
This patch is a follow-up of !14680 and changes setElems/mapToList in
GHC/Cmm/Dataflow/Label to use coerce instead of mapping mkHooplLabel
over the keys.

Reject infix promoted data constructors without DataKinds
In the rename, make sure to apply the same `DataKinds` checks for both
`HsTyVar` (for prefix promoted data constructors) and `HsOpTy` (for infix
promoted data constructors) alike.
Fixes #26318.

base-exports: update version numbers
As the version of the compiler has been bumped, a lot of the embedded
version numbers will need to be updated if we ever run this test with
`--test-accept` so let's just update them now, and keep future diffs
clean.

Import new name for 'utimbuf' on windows to fix #26337
Fixes an `-Wincompatible-pointer-types` instance that turns into an error on
recent toolchains and surfaced as such on nixpkgs when doing linux->ucrt cross.
This long-standing warning has been present at least since 9.4:

Adds the fucnction addDependentDirectory to Q, resolving issue #26148.
This function adds a new directory to the list of things a module depends upon. That means that when the contents of the directory change, the recompilation checker will notice this and the module will be recompiled. Documentation has also been added for addDependentFunction and addDependentDirectory in the user guide.

Fix deep subsumption again
This commit fixed #26255:
commit 56b32c5a2d5d7cad89a12f4d74dc940e086069d1
Author: sheaf <sam.derbyshire@gmail.com>
Date: Mon Aug 11 15:50:47 2025 +0200
Improve deep subsumption
This commit improves the DeepSubsumption sub-typing implementation
in GHC.Tc.Utils.Unify.tc_sub_type_deep by being less eager to fall back
to unification.
But alas it still wasn't quite right for view patterns: #26133.
This MR does a generalisation to fix it. A bit of a sledgehammer to crack
a nut, but nice.
* Add a field `ir_inst :: InferInstFlag` to `InferResult`, where
```
data InferInstFlag = IIF_Sigma | IIF_ShallowRho | IIF_DeepRho
```
* The flag says exactly how much `fillInferResult` should instantiate
before filling the hole.
* We can also use this to replace the previous very ad-hoc `tcInferSigma`
that was used to implement GHCi's `:type` command.
