This bug, revealed by #18347, is just a missing update to
sc_hole_ty in simplCast. I'd missed a code path when I

Implement cast worker/wrapper properly
The fix is very easy.
Two other minor changes
* Tidy up in SimpleOpt.simple_opt_expr. In fact I think this is an
outright bug, introduced in the fix to #18112: we were simplifying
the same coercion twice *with the same substitution*, which is just
wrong. It'd be a hard bug to trigger, so I just fixed it; less code
too.
* Better debug printing of ApplyToVal
