Re: [tree-ssa] PATCH to &&/|| gimplification


    Well, the mental model
    Richard and I hashed through a while back was that we'd do most loop
    optimizations at the tree level, but that we'd need a simplified loop
    optimizer to run on RTL as well.  Once we lower to RTL there's going
    to be some stuff exposed for LICM and possibly some strength
    reductions.

I don't follow.  Most strength reduction opportunities are in addressing
calculations and those you don't see until RTL.
