Well, one of the reasons I'm *not* looking into the two loop-unrolling
bugs that turn up on the i[3456]86 targets is that Michael Hayes is
rewriting this stuff - it feels like wasted effort.

I'm still interested in solving the one -Os failure - it's cute.  It
only fails on i[3456]86 and mips, AFAICS.
