That looks more SSAPRE than the patch (or, better, it happens if
you specify -O=ssapre and disappears otherwise).
SSAPRE and fastdce *cannot* happen togather (if SSAPRE is in, then
SSA is built, and in the patch the JIT falls back to SSA deadce).
Anyway, I still have to fully debug this, but this doesn't seem to
involve fastdce here.

I'll investigate more...
