Ping.

For reference, I mentioned this patch in a related discussion about instcombine and folding of cmps:
http://lists.llvm.org/pipermail/llvm-dev/2017-July/115452.html

Based on that thread, I think we do want to proceed with this canonicalization, rather than the inverse transform suggested in:

...but let me know if there's a better way.
