I'm not sure how there can ever be an "easy" workaround to silent
miscompiles -- by definition you may not know there is a problem to
work around until months later when the problem reports start coming
in from the field.

So I'm inclined to support a rigid rule that silent miscompiles are
the worst of all bugs, worse than ICE and worse than reject-valid.
