<pre>...aaannndd actually what was happening here was my half-baked debuginfo
metadata being wrong, and me missing the warning that LLVM was dropping most of
it. Curses, and apologies for the excess noise.
There's still something flaky involving CGPs sinking of addresses: it only
RAUW's one Value, and dbg.values can refer to components of the address that
aren't the final Value that gets dereferenced. However I'll open a different
bug for that, when I get a reproducer that Actually Works (TM).</pre>
