Add a final demand analyzer run right before TidyCore
in order to have precise used-once information in the exported
strictness signatures, as well as precise used-once information on
thunks. This avoids the bad effects of #11731.
The subsequent worker-wrapper pass is responsible for removing the
demand environment part of the strictness signature. It does not run
after the final demand analyzer pass, so remove this also in CoreTidy.
The subsequent worker-wrapper pass is also responsible for removing
used-once-information from the demands and strictness signatures, as
these might not be preserved by the simplifier. This is _not_ done by
CoreTidy, because we _do_ want this information, as produced by the last
round of the demand analyzer, to be available to the code generator.
