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.
Closes #22461.

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.

The RHS was too large to inline which often prevented the overhead of the Maybe
from being optimized away. By marking it as INLINE we can eliminate the
overhead of both the maybe and are able to unpack the accumulator when
possible.
