tree-loop-optimize is new to the lno branch.

Well, this is what a "man gcc" says on my system, when I'm using tree-ssa:

       -ftree-loop-optimize
           Perform loop optimization on trees.  This flag is enabled by
           default at -O and higher.

Oh, well, that one does nothing, since the optimizations were only implemented in the lno-branch.
:)

That flag is probably left over from before this was decided.
