Differentiate consumesReference and movesReference
Summary:
refcount opts assumes that a consumesReference instruction will reduce
the refcount immediately, but many such instructions simply teleport
the value elsewhere. For those cases, we can just bump up the
unsupported_refs, rather than reducing the lower_bound.
