-Wunused-pattern-binds: Recurse into patterns to check whether there's a splice

See the examples in #22057 which show we have to traverse deeply into a
pattern to determine whether it contains a splice or not. The original
implementation pointed this out but deemed this very shallow traversal
"too expensive".

Fixes #22057

I also fixed an oversight in !7821 which meant we lost a warning which
was present in 9.2.2.

Fixes #22067

Clean up some. In particular:
• Delete some dead code, largely under `GHC.Utils`.
• Clean up a few definitions in `GHC.Utils.(Misc, Monad)`.
• Clean up `GHC.Types.SrcLoc`.
• Derive stock `Functor, Foldable, Traversable` for more types.
• Derive more instances for newtypes.

Bump haddock submodule.

driver: pass original Cmm filename in ModLocation

When compiling Cmm, the ml_hs_file field is used to indicate Cmm
filename when later generating DWARF information. We should pass the
original filename here, otherwise for preprocessed Cmm files, the
filename will be a temporary filename which is confusing.

rts: make threaded ways optional

For certain targets (e.g. wasm32-wasi), the threaded rts is known not to
work. This patch adds a "threaded" cabal flag to rts to make threaded
rts ways optional. Hadrian enables this flag iff the flavour rtsWays
contains threaded ways.
