[Phab test] Testing expansion of O0 O3 etc.

[silvas]

Summary

I'm mostly interested in how Phab expands this when it sends an email. (right now it will expand at O3 we ... to
2Zhttps://reviews.llvm.org/owners/package/3/ we ...` which is annoying).

Sorry for the noise. You can safely ignore this patch.
