This isn't needed now, but will be once I implement the phase in bug 185060.
        
This could be a speed-up, or a slow-down, independent of that phase. Most likely it's neutral.
Local testing seems to suggest that it's neutral. Anyway, whatever it ends up being, I want it to
be landed separately and measured separately from that phase.
        
It's probably nice for sanity to have this and reduceStrength run before tail duplication and
another round of reduceStrength, since that make for something that is closer to a fixpoint. But
it will increase FTL compile times. So, there's no way to guess if this change is good, bad, or
neutral. It all depends on what programs typically look like.
