Previously, the demand signature we computed upfront for a DataCon wrapper
lacked boxity information and was much less precise than the demand transformer
for the DataCon worker.
In this patch we adopt the solution to look through unfoldings of DataCon
wrappers during Demand Analysis, but still attach a demand signature for other
passes such as the Simplifier.
See `Note [DmdAnal for DataCon wrappers]` for more details.
Fixes #22241.

See https://github.com/haskell/core-libraries-committee/issues/51 for
discussion. The key points driving the implementation are the following
two ideas:
* For the `Int` type, `comparing (complement @Int)` behaves exactly as
an order-swapping `compare @Int`.
* `enumFrom @(Down a)` can be implemented in terms of `enumFromThen @a`,
if only the corner case of starting at the very end is handled specially

GHC tests the exact print annotations using the contents of
utils/check-exact.
The same functionality is provided via
https://github.com/alanz/ghc-exactprint
The latter was updated to ensure it works with all of the files on
hackage when 9.2 was released, as well as updated to ensure users of
the library could work properly (apply-refact, retrie, etc).
This commit brings the changes from ghc-exactprint into
GHC/utils/check-exact, adapting for the changes to master.
Once it lands, it will form the basis for the 9.4 version of
ghc-exactprint.
