<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Introduce isBoxedTupleDataCon and use it to fix #18644
The code that converts promoted tuple data constructors to
`IfaceType`s in `GHC.CoreToIface` was using `isTupleDataCon`, which
conflates boxed and unboxed tuple data constructors. To avoid this,
this patch introduces `isBoxedTupleDataCon`, which is like
`isTupleDataCon` but only works for _boxed_ tuple data constructors.
While I was in town, I was horribly confused by the fact that there
were separate functions named `isUnboxedTupleCon` and
`isUnboxedTupleTyCon` (similarly, `isUnboxedSumCon` and
`isUnboxedSumTyCon`). It turns out that the former only works for
data constructors, despite its very general name! I opted to rename
`isUnboxedTupleCon` to `isUnboxedTupleDataCon` (similarly, I renamed
`isUnboxedSumCon` to `isUnboxedSumDataCon`) to avoid this potential
confusion, as well as to be more consistent with
the naming convention I used for `isBoxedTupleDataCon`.
Fixes #18644.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">configure: Avoid hard-coded ld path on Windows
The fix to #17962 ended up regressing on Windows as it failed to
replicate the logic responsible for overriding the toolchain paths on
Windows. This resulted in a hard-coded path to a directory that likely
doesn't exist on the user's system (#18550).

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">gitlab-ci: Bump Docker images
We now generate our Docker images via Dhall definitions, as described in
ghc/ci-images!52. Additionally, we are far more careful about where tools
come from, using the ALEX, HAPPY, HSCOLOR, and GHC environment variables
(set in the Dockerfiles) to find bootstrapping tools.

Previously hadrian would use GHC on PATH when configuring packages (or
fail if there is no such GHC). Fix this. Unfortunately this runs into
another bug in Cabal which we workaround.
