<pre>I committed the fix proposed below in r275053. This addresses the most obvious
issues and should make the buildbots green again.
We may still need to review the load hoisting code more carefully. The fact
that the run-time check we construct does not take into account the
invalid-assumptions we derive for memory accesses looks rather fragile and
would clearly benefit from some further review and testing. Unfortunately,
Johannes is currently not available to help with these issues.</pre>
