    Being able to optimize at the tree level.  I disbelieve we'll
    be able to do that properly given the less than precise
    semantics of SAVE_EXPR.

I don't follow.  For most purposes of tree-level optimization they are
nops, except that they aren't invalidated by stores to things that are in
the expression in their operand.
