It turns out we can codegen these on targets without flat addressing,
although the runtime probably didn't put anything useful there. The
proper diagnostic would be to disallow flat pointer uses or languages
with them, not this one edge case. Allows removing one of the special
cases requiring subtarget support in the device libraries.
