In this job we can run on every commit we add a test which builds the
Cabal library twice and checks that the ABI hash and interface hash is
stable across the two builds.
* We run the test 20 times to try to weed out any race conditions due to
`-j`
* We run the builds in different temporary directories to try to weed
out anything related to build directory affecting ABI or interface
file hash.

The idea is that both the bindists should product libraries with the
same ABI and interface hash.
So the job checks with ghc-pkg to make sure the computed ABI
is the same.
In future this job can be extended to check for the other facets of
interface determinism.

There was some code in the signature merging logic which added together
the ImportAvails of the signature and the signature which was merged
into it. This had the side-effect of making the merged signature depend
on the signature (via a normal module dependency). The intention was to
propagate orphan instances through the merge but this also messed up
recompilation logic because we shouldn't be attempting to load B.hi when
mergeing it.
The fix is to just combine the part of ImportAvails that we intended to
(transitive info, orphan instances and type family instances) rather
than the whole thing.

In #22217 it was observed that the order modules are compiled in affects
the contents of an interface file. This was because a module dependended
on another module indirectly, via a re-export but the interface file for
this module was never loaded because the symbol was never used in the
file.
If we decide that we depend on a module then we jolly well ought to
record this fact in the interface file! Otherwise it could lead to very
subtle recompilation bugs if the dependency is not tracked and the
module is updated.
Therefore the best thing to do is just to make sure the file is loaded
by calling the `loadSysInterface` function. This first checks the
caches (like we did before) but then actually goes to find the interface
on disk if it wasn't loaded.
Fixes #22217

So that we get to cancel away the allocation for the lazily used base.
We can move `powImpl` (which *is* strict in the base) to the top-level
so that we don't duplicate too much code and move the SPECIALISATION
pragmas onto `powImpl`.
The net effect of this change is that `(^)` plays along much better with
inlining thresholds and loopification (#22227), for example in `x2n1`.
Fixes #22324.

There was some confusion in Data.Typeable about which module certain
wired-in things were defined in. Just because something is wired-in
doesn't mean it comes from GHC.Prim, in particular things like LiftedRep
and RuntimeRep are defined in GHC.Types and that's the end of the story.
Things like Int#, Float# etc are defined in GHC.Prim as they have no
Haskell definition site at all so we need to generate type
representations for them (which live in GHC.Types).

The Lint check for branch compatiblity within an axiom, in
GHC.Core.Lint.compatible_branches was subtly different to the
check made when contructing an axiom, in
GHC.Core.FamInstEnv.compatibleBranches.
The latter is correct, so I killed the former and am now using the
latter.
On the way I did some improvements to pretty-printing and documentation.
