* Always expose the unfolding of something with an InlineRule
Ignore-this: 4f952f423848b8840fab69d63ee81d8f
Previously a bottoming function with a strictness wrapper
had a hidden inlining, and that was Very Bad, because in
f x = if ... then bot_fun x else x+1
we really want to pass the *unboxed* x to bot_fun. This
happens quite a bit in error handling code, eg for array
indexing.
