We need more analysis on these kinds of issues.

So, we're doing a worse job on register allocation.  Is that because the
register allocator got worse, or because we're giving it a harder problem to
solve?  If the latter, what's responsible, and is there anything we can do
about it?  We need that kind of information to make an intelligent decision
about whether or not we should try to fix this, or just chalk it up to the fact
that there's always variability between releases.
