Expose compulsory unfoldings always
The unsafeCoerce# patch requires that unsafeCoerce# has
a compulsory unfolding that is always available. So we have
to be careful to expose compulsory unfoldings unconditionally
and consistently.
We didn't get this quite right: #17871. This patch fixes
it. No real surprises here.
