Ok, please work on this as a follow-up patch.

I committed the patch in r96011.  However, please do follow up with the replaceUsesOfWithOnConstant thing above, and please add a note to the release notes mentioning the feature and saying that it may change in the future.

Also, please read the llvm developer policy doc and send me the requested info and I'll set you up with commit access, thanks!
