Re: [lno] tree-ssa --> lno merge

thanks.
bootstrap & vectorization tests passed on powerpc-apple-darwin7.0.0

I get a few spec failures; I'm not sure it's related to the  recent merge,
because it's the first time I'm using -ftree-loop-optimize. Below are the
two errors that I'm getting.

thanks,
dorit

Hello,

I have merged tree-ssa into lno branch, so if something breaks you know
who to shout at :-)
