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.

We didn't consider the RHS of a pattern-binding before, which led to

surprising warnings listed in #18572.

As can be seen from the regression test T18572, we get the expected

output now.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PmCheck: Big refactor using guard tree variants more closely following source syntax (#18565)

Previously, we desugared and coverage checked plain guard trees as

described in Lower Your Guards. That caused (in !3849) quite a bit of

pain when we need to partially recover tree structure of the input

syntax to return covered sets for long-distance information, for

example.

In this refactor, I introduced a guard tree variant for each relevant

source syntax component of a pattern-match (mainly match groups, match,

GRHS, empty case, pattern binding). I made sure to share as much

coverage checking code as possible, so that the syntax-specific checking

functions are just wrappers around the more substantial checking

functions for the LYG primitives (`checkSequence`, `checkGrds`).

The refactoring payed off in clearer code and elimination of all panics

related to assumed guard tree structure and thus fixes #18565.

I also took the liberty to rename and re-arrange the order of functions

and comments in the module, deleted some dead and irrelevant Notes,

wrote some new ones and gave an overview module haddock.
