[tree-ssa] Branch unfrozen

[Diego Novillo]

It doesn't look like keeping the branch closed will help much more.  PPC
is also broken on mainline as of 2003-05-25.  I'm testing on today's
mainline.  If it works, I'll do an incremental mini-merge.

Go ahead and check what you guys have.  I'd rather fix all the remaining
problems with overlapping live ranges than finish the merge.  I'll keep
working on fixing things on this merge and incorporate the fixes as you
commit them into the branch.


Diego.
