For an expression like:
case x of y
Con z -> z
If we also retain the tag sig for z we can generate code to immediately return
it rather than calling out to stg_ap_0_fast.

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

Rather than a list of constructors and a `NewOrData` flag, we define `data DataDefnCons a = NewTypeCon a | DataTypeCons [a]`, which enforces a newtype to have exactly one constructor.
Closes #22070.
