We were missing a call to `decideBangHood` in the pattern-match checker.
There is another call in `matchWrapper.mk_eqn_info` which seems redundant
but really is not; see `Note [Desugaring -XStrict matches in Pmc]`.
Fixes #21761.

As discovered in #22272, dehydration of the unfolding info of a
recursive definition used to involve a traversal of the definition
itself, which in turn involves traversing the unfolding info. Hence,
a loop.
Instead, we now store enough data in the interface that we can produce
the unfolding info without this traversal. See Note [Tying the 'CoreUnfolding' knot]
for details.
Fixes #22272

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.
