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.

The Lint check for branch compatiblity within an axiom, in

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.

Previously, the `checkValidInst` function (used when checking that an instance
declaration is headed by an actual type class, not a type synonym) was using
`tcSplitSigmaTy` to split apart the `forall`s and instance context. This is
incorrect, however, as `tcSplitSigmaTy` expands type synonyms, which can cause
instances headed by quantified constraint type synonyms to be accepted
erroneously.
This patch introduces `splitInstTyForValidity`, a variant of `tcSplitSigmaTy`
specialized for validity checking that does _not_ expand type synonyms, and
uses it in `checkValidInst`.
Fixes #22570.

Previously the dump filename cache would use a non-atomic update which
could potentially result in lost dump contents. Note that this is still
a bit racy since the first writer may lag behind a later appending
writer.

In the wasm NCG, when handling a `CLabel` of undefined function
without knowing its function signature, we used to fallback to `() ->
()` which is accepted by `wasm-ld`. This patch changes it to the
signature of Cmm functions, which equally works, but would be required
when we emit tail call instructions.

When the `-mtail-call` clang flag is passed at configure time, wasm
tail-call extension is enabled, and the wasm NCG will emit
`return_call`/`return_call_indirect` instructions to take advantage of
it and avoid the `StgRun` trampoline overhead.

0e274c39bf836d5bb846f5fa08649c75f85326ac added an assertion in
`dirty_MUT_VAR` checking that the MUT_VAR being dirtied was clean.
However, this isn't necessarily the case since another thread may have
raced us to dirty the object.

As noted in #22538, previously some GCC versions warned that various
locals in Libdw.c may be used uninitialized. Although this wasn't
strictly true (since they were initialized in an inline assembler block)
we fix this by providing explicit empty initializers.

We used to use keepCAFsForGHCi.c to force -fkeep-cafs by using a
__attribute__((constructor)) function.
Besides being an odd choice this broke for static builds where
the constructor function was never called. Yuk.
So instead we now just tell cabal to compile the relevant files with
-fkeep-cafs.
