Sigh.  Another SSA_NAME flowing through EH edges getting in the
way.

I'm starting to think that it would be much better to make these
SSA_NAME_OCCURS_IN_ABNORMAL_PHI into virtuals.  We would avoid
all the monkeying around that optimizers have to do.  It would
involve a bit of trickery because we only detect them when they
first go into SSA form, but it's doable.  Comments from EH folks?

But we loose too much optimizations in C++.

Not committed yet.  Mainline is segfaulting somewhere in libjava
with and without my patch.  Somewhere in final code generation.
I still haven't looked hard.

Could anyone with access to a darwin machine test this patch for
me?

I will test this soon.

Thanks,
Andrew Pinski
