Agree that experimentation should be done with local changes to LLVM.

Options like these tend to get added and never removed, even if they have outlived their usefulness. I could kind of see the rationale for adding it to LoopRotate (which is well-known to be problematic in this regard, and it's plausible to assume that more than one organization would have interest in testing the option), but I wouldn't want to encourage this as a general pattern for exploration of minsize optimization changes.
